摘要

在平面应变条件下，对采用水泥搅拌桩复合土钉支护的基坑进行了有限元数值模拟，在此基础上采用有限元稳定分析方法评价基坑的稳定性。通过对复合土钉工作机理的分析，并与普通土钉支护的基坑进行比较，分析二者的差异。通过分析不同支护参数的影响，研究基坑的变形以及稳定性变化规律，为设计和施工提供一定的参考依据。

Abstract

Based on the theory of plane strain

2D elastoplastic FEM is used to analyze the behavior of composite soil nailing support of deep foundation pit

and evaluate the stability of the soil-nailed wall. The difference between composite soil nailing support and normal soil nailing support are compared; and the influence of supporting parameters on the deformation behavior and stability of foundation pit are analyzed. Some useful conclusions are drawn to supervise the design and construction.
