In order to study the influence of reinforcement ratio on the ductile seismic performance of reinforced concrete bridges, the reasonable value of main reinforcement ratio was subdivided in different fortification intensity. Taking reinforced concrete bridge as the research object, the relationship between vertical reinforcement ratio and pier ductility was studied by means of quasi-static model test and finite element numerical analysis, and the quantitative index of multi-stage performance level of typical piers was put forward. And the influence of different reinforcement ratio on the seismic performance of bridges in the harsh environment of chloride erosion was also explored, so as to provide reference suggestions for the range of reinforcement ratio of small and medium-span bridge piers in the earthquake area under chloride erosion environment. The results show that the restoring force model under chloride erosion can better reflect the degradation characteristics of stiffness, and the range of the optimal reinforcement ratio of piers is 1. 11% ~ 2. 72% . When the acceleration is 0. 3g (g is the gravitational acceleration), the damage index of piers can not be satisfied only from the point of view of reinforcement ratio. It is suggested that seismic isolation system should be used for seismic design, such as ductility system, the reinforcement ratio should not be less than 2. 64% . The research results can provide reference for the revision of seismic code for small and medium-span continuous bridges. [ABSTRACT FROM AUTHOR]

Objectives: For the high-reliability and fast cycle slip detection and correction of high-samplingrate global navigation satellite system (GNSS) data, the quality control method for modified geometry-free (MGF) combination is proposed to improve the success rate of phase cycle slip correction. Methods: According to the MGF combination and its error characteristics, the error limits of the MGF method are derived, and the applicability in different navigation satellite systems and the influence of measurement noise on the detecting results are analyzed. Based on the above research, the quality control test of the MGF com ‑ bination is constructed and multi-GNSS experiments are carried out. Results: The experimental results show that the MGF method can be used to detect and correct small cycle slips (such as cycles below 5) rapidly with an accuracy rate of 99.90%. Besides, the quality control test of the MGF combination can identify 100%, 87.57% and 77.42% of the wrong correcting results of GPS, BDS and GLONASS respectively, which reduces the error rate of cycle slip correction to 0.01%.Conclusions: The MGF method is significantly influenced by the noise of phase observation, and the quality control test can identify wrong correcting results effectively, thereby improving the success rate of cycle slip correction. The ability of the quality control test to distinguish wrong detecting results and noise decreases with the increase of noise level. [ABSTRACT FROM AUTHOR]
