基坑开挖中的环境岩土工程问题研究

Study on the environmental geological engineering problems associated with excavation of foundation pits

基坑工程是一涉及岩土工程、结构工程和环境工程等众多学科领域的综合工程 ,基坑工程往往是在城市中心地带建筑密集区进行 ,基坑工程的建设 ,不仅受周围环境的限制 ,也对周围环境会造成不同程度的影响 ,因此 ,研究基坑开挖中环境岩土工程地质问题有重要意义。本文分析了基坑开挖中环境岩土工程地质现象的主要类型 ,探讨了这些类型之间的有机联系和环境岩土工程地质现象变异的危害 ,并提出了基坑开挖中预防环境岩土工程地质现象发生的途径与措施。

Foundation pit engineering is a synthetical engineering which relates to numerous subject field′s, such as geotechnical engineering,engineering geology, structural engineering, environmental engineering, etc.Foundation pits are often constructed in compression area of buildings of urban centre zone, the construction of foundation pits is not only restricted by around environment, but also affects around environment in different extent. Therefore, it is very important to study the environmental geotechnical engineering problems associated with excavation of foundation pits.In this paper,main types and harms of the environmental geotechnical engineering problems associated with excavation of foundation pits are analysed, organic relation among these types are discussed, prevention approaches and measures of these problems are also proposed.
