深基坑土钉墙与桩锚联合支护结构数值模拟与优化

Numerical Simulation and Optimization of Deep Foundation Soil Nail Wall and Pile Anchor Combined Support Structure

为解决现有基坑开挖施工中存在支护桩设置不合理,造成地表沉降过大,影响施工质量的问题,开展深基坑土钉墙与桩锚联合支护结构数值模拟与优化研究。结合深基坑土钉墙与桩锚联合支护结构数值模拟得到的结果,对支护桩间隔距离、支护桩嵌固深度进行优化。采用优化后的施工方案可以实现对基坑地表沉降量的有效控制,提升工程整体施工质量。

In order to solve the problem of unreasonable setting of support piles in existing foundation pit excavation construction,which leads to excessive surface settlement and affects construction quality,numerical simulation and optimization research on the combined support structure of deep foundation pit soil nail wall and pile anchor were carried out.Based on the numerical simulation results of the combined support structure of deep foundation pit soil nail wall and pile anchor,the spacing distance and embedding depth of the support piles were optimized.The optimized construction plan can effectively control the surface settlement of the foundation pit and improve the overall construction quality of the project.
