微型桩—锚杆联合支护体系加固基坑效果的数值分析

Numerical analysis of the effect of micro pile-anchor combined support strengthening the foundation pit

用有限元软件模拟了微型桩—锚杆联合支护在某基坑中的应用,并分析了其在基坑开挖过程中对基坑底部及周边地层的保护效果,结果表明,微型桩—锚杆联合支护对限制基坑壁的水平位移效果显著,并且能够有效地减少基坑开挖对周边地层的影响范围。

Simulated the use of micro pile-anchor combined support in the application of a foundation pit, and analyzed its protective effect on surrounding soil and pit bottom in the process of excavation of foundation pit. The resuhs show that the micro pile-anchor combined support can restrict horizontal displacement of pit wall remarkably, and can effectively reduce the influence of excavation on surrounding strata.
