| 摘 要： | 在考虑基坑内工程桩存在的前提下，采用有限元法分析不同的地连墙深度、地连墙刚度和土体刚度对基坑变形的影响，并与不考虑工程桩存在的情况作比较．研究结果表明，土体刚度对基坑变形的影响最显著，工程桩的存在会对基坑变形、支护结构内力产生一定的影响，在深基坑工程的设计和研究中不应忽略工程桩的影响．

| Abstract: | On the premise that considering foundation piles, the different diaphragm wall depth and stiffness, the different soil stiffness that influencing the pit deformation are analyzed by the finite element method. At the same time, the deformation is compared with the deformation without foundation piles. The result indicates that the soil stiffness has rather significant effects on the pit deformation. Foundation piles have definite effects on the pit deformation and internal forces of exterior-protected constructions. Foundation piles can not be neglected in the design and research of the pit engineering. |
