For over half a century,Chinese geotechnical investigation professionals witnessed continuous technical advances as they undertook independently almost all of China's large-scale construction projects. Based on projects that won the "National Outstanding Engineering Investigation" Gold Medal Awards since the year 2000,this paper discusses the achievements of geotechnical investigation in the context of comprehensive technical ability,project evaluation and analysis,hi-tech applications and engineering monitoring,and analyzes several factors that have hindered the industry's further development and alignment with international practice. Finally,some suggestions are given for future improvement.展开更多

Moreover, over the years, I have enjoyed looking through the issues of the existing Chinese Journal of Rock Mechanics and Engineering （CJRME）. The content of this Journal, initiated in 1982, is partially accessible to foreigners because the Contents, paper Abstracts and Figure captions are published in English. The number of rock mechanics articles in each monthly issue of the Journal is far more than any other country can produce. This activity is also reflected in the fact that China now has more ISRM members （502） than any other country -- and the number is no doubt continuing to grow! Furthermore, the Editor-in-Chief of the CJRME, Professor Feng Xiating, will be the next ISRM President for the period 2011-2015.展开更多

In order to ensure the stability and safety of buildings, we must improve the attention to the design of deep foundation pit supporting. However, no matter from which point of view of geotechnical engineering, there are some problems, such as unreasonable mechanical parameters selected and weak representative sampling of soil in deep foundation pit. These problems are not conducive to promoting the design and construction of deep foundation pit support. For this reason, the problems existing in the design and construction are taken as the starting point. Then, according to the existing problems, countermeasures are put forward from three aspects: scientific mechanical parameters selection, advanced design methods application and scientific sampling.展开更多

Nowadays, geotechnical engineering is not only increasing in quantity but also expanding in scale. Facing the current situation of geotechnical engineering, how to promote the benign development and progress of geotechnical engineering is a problem that is worth thinking about, and is also the focus of professional research on geotechnical work in our country at this stage. For geotechnical construction engineering, the investigation work and hydrogeological problems are a part worthy of in-depth study. The investigation work and hydrogeological conditions will directly affect the normal advancement of geotechnical engineering. Therefore, fully grasping the key points of investigation and grasping the geological and hydrogeological conditions is the key to ensure the smooth development of subsequent construction work. Relevant professionals should be familiar with the key points of survey and construction procedures. According to the actual situation of the construction team and the specific analysis of the specific situation, the construction work and survey work should be carried out in a targeted manner so as to avoid the risks and deficiencies of a series of survey activities that may occur in the practical operation process as far as possible, thus ensuring the final construction effect.展开更多

In this process, the exploitation of resources has seriously damaged the environment. The development of urban economy cannot be separated from the development of geotechnical engineering, which is in great demand. Mining will cause environmental damage, and all kinds of geological disasters occur more frequently, such as debris flow, landslide and mountain collapse. In addition to affecting the natural ecological environment, disasters also pose a great threat to people's lives and property safety. Therefore, it is necessary to explore the prevention and control technology of related disasters as well as the pre-control issues.展开更多

However, due to the influence of geological conditions in the whole construction process of the project, the geotechnical slope construction faces many problems, especially the stability of the slope. If the slope construction quality cannot be guaranteed, the engineering construction of the whole project will be affected. In geotechnical engineering, slope reinforcement engineering has strong complexity and many influencing factors. It is necessary to select appropriate construction technology in combination with geological conditions in order to better ensure the construction quality. Compared with anti slide pile, anchor bolt support and other construction technologies, prestressed anchor cable construction technology has more significant advantages in construction quality, construction efficiency and greening, which is worthy of wide application.展开更多
