Conducting vertical control network for super-span cross-river bridges is a key and challenging aspect of bridge construction measurement. Considering requirements of the vertical control network in Changtai Yangtze River Bridge project, the principle of total station ATR technology was studied from the aspects of cross-river line selection, cross-river points determination, vertical angle measurements and trigonometric leveling. The influence of distance, angle and atmospheric refraction on height difference measurement was investigated. Finally, the second order cross-river leveling data of total station with a crossriver distance of 2.97 km was analyzed. The maximum difference between the two circles after averaging was 9.99 mm, which was much smaller than the tolerance. The maximum ring closing difference was 8.89 mm, which met the requirement of tolerance. The random error of mean round-trip measurement was ±0.34 mm/km, which met the requirement of second order leveling accuracy. It is concluded that the total station ATR technique could be used for cross-river leveling for bridges with lengths less than 3.0 km, and the accuracy meets the second order leveling. Compared to traditional manual aiming measurement methods, the ATR technology of total stations can significantly improve measurement efficiency and enable intelligent cross-river leveling.

Wuhu Straddle-type Monorail Line 1 and Line 2 run through the main urban area of Wuhu along the north-south and east-west directions respectively, and the urban investigation environment and geotechnical conditions are complicated. In Wuhu viaduct station, the single-column large cantilever structure concept of "bridge construction in one" is used, and the continuous steel track beam bridge is used in the section, which has its special structural form. As a special standard of rail transit, straddle monorail has no specific description and technical requirements in the current survey standards, which requires higher requirements for the survey work. To solve the karst problem, the karst exploration methods were combined with ground electric method, geological radar (single hole radar, cross hole radar CT) and drilling. To solve the problem of soft soil, the methods of in situ test and laboratory test, such as lateral expansion of flat shovel, cross plate shear and static penetration were used. To solve the hydrogeological problems, the methods of hydrology investigation with "one drawing and three observations" hydrology experiment, long-term hydrology observation and laboratory experiment were adopted. The research shows that the comprehensive survey technology can fully identify the karst distribution and development characteristics, soft soil characteristics and mechanical property differences, accurately determine the hydrogeological parameters, and rationally optimize the anti-floating design.

Taking the Dengkou Bridge on the Yellow River for Baotou -Yinchuan high -speed railway for example, the changing of the waterfronts and sand banks in the wandering reaches, where the bridge is located, and the changing of the cross sections of the river bed are analyzed. Measures to build multiple spans over the changing width of the main channel and reasonably arrange the bridge spans were proposed as the selection of the bridge site could not meet the requirements speculated in Navigation standard of inland waterways and the selection cannot be adjusted. Through the study of the channel layout under the existing conditions, the bridge span plan was optimized and adjusted so that the 4伊178mmain span in the current main channel can meet the requirements of the two-way navigation for representative ships, and the right side span and the side span on the left side of the banks can meet the requirements of one-way navigation for representative ships. The navigable multiple spans of the bridge have covered the changing range of the main channel. The navigable conditions of the channel are satisfied without implementing sand bank and channel protection and channel regulation, and the harmonious and win-win situation of bridge construction and channel protection is realized, which provides certain reference for the bridge design of the same type of project.

The construction technology of precast segment is of great significance in promoting green, low-carbon and sustainable development of bridge construction. In order to expand the application range of segmental prefabrication technology, it needs to be further researched and improved. According to the research results of prefabricated and assembled bridges at home and abroad, the research progresses of the overall performance evaluation of the bridge, joint design, key construction technology and simulation analysis are reviewed. The results show that researches are insufficient on such problems as structural adhesive aging and adhesive-concrete interface aging, uneven distribution of shear stress of key teeth, mechanical properties of joints under the combined action of bending, bending and shearing; researches are absent on the theory related to segmental precast bridge construction technology; and researches are few on the whole process of construction structure simulation and simulation analysis. In view of the problems existing in the research on segmental precast bridge technology, it is necessary to further improve the theoretical research on segmental precast bridge, formulate corresponding specifications, increase the research on key technology in design and construction, strengthen information management and realize the development of the whole life cycle, etc. [ABSTRACT FROM AUTHOR]

In order to ensure the safety and stability of the construction process of the bidirectional outward inclined arch tower cable-stayed bridge, the optimization design method of construction measures is put forward. The objective function of optimization is the safety and economy of construction measures. The stress safety of cable-stayed bridge in each construction stage is the constraint condition. The construction method of cable-stayed bridge is optimized by determining the position and structure form of construction measures. The prestressed concrete cable-stayed bridge with single tower and double cable plane in the shape of golden camellia is taken as the engineering background. The position and causes of the hidden danger in the construction of the bridge are analyzed. This method is applied to optimize the construction method, and three cross bracings are to be set up in the construction stage of the main tower. The optimized construction method is applied to actual construction. The results show that this method can design better construction measures. The optimized construction method effectively controls the stress and line shape of the main bridge during the construction phase. The maximum tensile stress of the main tower is controlled at 1. 67 MPa, and the maximum horizontal displacement of the tower top is maintained at 14. 50 mm. The stress state of the main bridge construction can meet the safety requirements. The measured stress of the main tower is consistent with the finite element calculation, and the error is within 5%. This method scientifically and effectively guides the construction and achieves good results. [ABSTRACT FROM AUTHOR]

The main bridge of the Chibi Yangtze River Highway Bridge is designed as a cable-stayed bridge with double tower and double cable plane. In order to optimize the mix proportions of the bridge tower concrete and understand the performance characteristics of the bridge tower concrete, the effects of single addition of fly ash (FA), and the compound of FA and ground blast furnace slag (GBFS) on the performance of the bridge tower C50 grade concrete were investigated, and the influence of mineral admixtures on the microstructure of the bridge tower concrete was analyzed by mercury porosimeter (MIP) and scanning electron microscope (SEM). The results show that the workability and strength of the bridge tower C50 concrete prepared with FA and GBFS composite admixtures meet the design and construction requirements, and its drying shrinkage value is low. Meanwhile, the bridge tower concrete prepared with FA and GBFS composite admixtures are better than the concrete with single addition of FA in early strength and strength development, elastic modulus, resistance to chloride ion permeability and anticarbonation of C50 concrete. Compared with single addition of FA, the composite additions of FA and GBFS had a better action on the refinement of pore structure and the improvement of microstructure of concrete.

Due to low accuracy of the traditional impedance admeasuring apparatus, a portable impedance admeasuring apparatus based on an automatic balance bridge is designed. In the apparatus, a test signal source is obtained by filtering a square wave signal and an I/V conversion circuit is constructed by using a high input-impedance operational amplifier, which leads to accurately measuring the current via a tested unit. After amplitude and initial phase angle of both voltage and current signals of the tested unit are acquired by using the pulse phase discriminating circuit, the impedance parameters of the tested unit are calculated in the single-chip microcomputer system. The experimental results demonstrate that the impedance admeasuring apparatus is of high accuracy and its maximum error is only 0.052% when measuring resistors or resistance-capacitance series-connection networks.

To optimize the design of girder bridge, the proper cell number of the two-lane CSWs PC box girder was investigated. Based on the two-lane CSWs PC box girder bridge design parameter, the mechanical behaviors of single-room girder box with single cell to five cells were analyzed under four different load conditions by finite element analysis (FEA).The mid-span displacement in the bottom flange, the von-Mises shear stress in both corrugated web sides, the normal warping stress and the natural frequency of the box girders were obtained. The results show that multiplying cell numbers can increase the prestressing efficiency and decrease the von-Mises shear stress in both corrugated web sides in some cases. However, with the cell number increasing, the normal warping stress under eccentric load and the dead weight of the girder are increased dramatically. By simple formula method and principal component analysis method, the proper cell number for the two-lane CSWs PC box girder is suggested. [ABSTRACT FROM AUTHOR]
