Problems and improvement measures of foundation pit support design in mine geotechnical engineering construction

针对矿山岩土工程施工过程中基坑支护的质量与安全影响问题,提出了矿山岩土工程施工过程中基坑支护的设计存在的问题和改进措施。发现存在力学参数选择不科学导致了设计与实际情况存在巨大误差的问题,针对这些问题提出了采用新型基坑设计方式和强化对基坑变形、基坑坍塌等实际问题的具体控制的解决措施,最后通过试验进行验证。

In view of the quality and safety impact of foundation pit support in the process of mine geotechnical engineering construction,the existing problems and improvement measures in the design of foundation pit support in the process of mine geotechnical engineering construction are put forward.It is found that the unscientific selection of mechanical parameters leads to the problem of huge error between the design and the actual situation.In view of these problems,the solution measures of adopting a new foundation pit design method and strengthening the specific control of foundation pit deformation,foundation pit collapse and other practical problems are put forward.Finally,it is verified by experiments.
