CO2 geological storage projects are an essential tool for China to achieve the double carbon target of energy savings and emission reductions. In order to safely and effectively control the implementation of injection projects and monitor the dynamics of CO2 injection, multi-dimensional and multi-disciplinary monitoring tools are required. Among them, microseismic monitoring is a key technology for predicting reservoir dynamics and reflecting reservoir geomechanical behavior. Such monitoring has been carried out previously for reservoirs in other countries, but experimental projects are also gradually being developed in China. In this paper, we focus on the research and analysis results of microseismic monitoring of carbon storage projects in various work areas. For different reservoir conditions, we explore combinations of the monitoring implementation methods in China, comparing the differences in each work area. We propose a joint well and ground microseismic monitoring method and a multi-spatial and multi-physical field coupling research system for use in the implementation of domestic demo projects for the future research and development of microseismic monitoring of carbon storage projects. The monitoring program can meet the requirements for certain periodic repeated or continuous observations and can intelligently assess the risk and handle the alert behavior. The foundation is laid for the development of the future microseismic monitoring technology to achieve the goal of developing cost-controllable, permanent, and real-time monitoring equipment. The application of the monitoring system in China has been effective, and this experience can contribute to the development of injection engineering in the future. [ABSTRACT FROM AUTHOR]

Nowadays, with the leap-forward development of computer technology and the transformation of information technology management concepts, China's construction industry is quietly entering the era of refined management. Accurate estimation and cost control have become among the key considerations of the construction industry. For the calculation of engineering quantity, there are already many software devices that can be used for the calculation of engineering structure quantity, which means that the incorrect operation of personnel has been reduced to some extent, improving the work efficiency and measurement accuracy. The purpose of this paper is to solve the problems of computational missing, computational errors, inefficiency, data loss, and repetitive system in traditional computing based on the advantages of BIM computing system, which provide a reliable basis for cost forecasting and control. At the same time, using BMI calculation system to solve the problem of steel reinforcement in construction engineering, as well as the use of personnel, the existing calculation software still needs a lot of time and energy. We proposed a comprehensive evaluation study of reinforcement calculation in domestic construction engineering BIM calculation system based on a fuzzy comprehensive evaluation. This paper first summarizes the BIM calculation system of construction engineering, uses fuzzy comprehensive evaluation system as an important evaluation index system in domestic construction engineering BIM calculation system, through the judgment of various factors affecting the actual effect of the calculation system, and uses the fuzzy evaluation system combined with a case to demonstrate the superiority of the proposed research. Therefore, through the above research and experiments, it is concluded that the research method of this paper solves many problems in the process of engineering structure reinforcement calculation and provides a good reference method for the establishment of comprehensive evaluation system of reinforcement calculation, as well as providing an effective validation for the widespread use of BIM technology in the construction industry. Finally, it is also beneficial for users to comprehensively evaluate the BIM calculation system of the construction industry and provide a basic reference condition for different industries to use and choose BIM calculation systems.

In this paper, we collected, summarized, and analyzed the available data of 143 transportation immersed tunnels at home and abroad, and analyzed the current state of the immersed tunnel engineering in the world from the aspects of construction quantity, construction length, construction speed and construction difficulty. Based on the quantifiable indexes of tube volume, tube number, water depth and buried depth, the evaluation formula of construction difficulty of immersed tunnel was put forward for the first time. Finally, based on the number of monographs, patents and papers, we analyzed and evaluated the scientific and technological development status of immersed tunnel in China. [ABSTRACT FROM AUTHOR]

Compared with contracting engineering projects in China, contracting international engineering projects is affected by many factors, with great risks and uncertainties. Risk control should be paid attention to and effective risk prevention should be carried out in bidding stage. In this paper, we summarized the common risks of international project bidding, and expounded the procedures and principles of international project pre - bidding organizations, and introduced the key points and countermeasures of risk prevention and control by studying bid documents and on -site investigation combining with a large number of practical engineering cases, so as to provide reference for Chinese enterprises who participate in international project bidding.

Under the influence of natural science, twentieth century philosophy departed from its Socratic heritage and increasingly isolated itself within the discipline. This new disciplinary way of doing philosophy produced a greater amount of professional knowledge and expertise, but it also separated philosophy from its broader social context. Since the mid-20th century, various efforts were made under a variety of banners to reconnect philosophical thinking with society, with field philosophy representing the most genuine break from the disciplinary paradigm. It advocates collaborative work and rejects philosophic jargon. It also shares much in common with a parallel Chinese approach called 'philosophy of gongcheng.' The philosophy of gongcheng is mostly initiated by top-level engineers, especially academicians with real political power, with the aim of enhancing the real-world engineering practices. This paper traces the roots of philosophy of jishu in China to reevaluate the appearance of philosophy of gongcheng, and exposes the differences between these two parallel transdisciplinary approaches. Working with engineers deepens the understanding of engineering practices and provides some fresh insights on previous philosophical theories. Both field philosophy and philosophy of engineering need to ask, is there only one way to do philosophy? [ABSTRACT FROM AUTHOR]

Ground pressure hazards in deep rock engineering, such as rock spalling and rock burst, are big challenges and threats to personnel and equipment safety. In order to investigate the mechanism of ground pressure disasters in deep rock engineering, in-situ investigations were carried out in a deep gold mine in China. The survey results show that with the increase of the mining depth, the number and severity of ground pressure disaster events increase significantly. The investigation results of ground pressure disaster in the gold mine are analyzed by three methods. The effects of the maximum tangential stress, strain rebound and strain energy release on the failure of surrounding rock under different burial depths are obtained. The failure behaviors of surrounding rock are well explained by these methods at different mining depths. The new method considering strain energy release can well explain the phenomenon of core disking and it can accurately calculate the theoretical thickness of core disk. In addition, a theoretical calculation basis for the support design of energy absorbing bolt is provided in the paper and the support design figure is put forward by considering energy absorbing bolt. • According to in-site investigations, ground pressure hazard events increased significantly with depth. • Strain energy released by surrounding rock increases rapidly with a function of second power of mining depth. • Phenomenon of core disking is well explained, and calculation formula of rock disk thickness is provided. • The energy-absorbing materials such as energy-absorbing bolts can well absorb the released strain energy.
