摘　　要：以采用阶式土钉墙支护形式的深基坑工程为例,运用FLAC3D数值分析软件建立计算模型,对深基坑开挖与支护过程进行模拟,给出土钉内力与基坑变形的数值模拟结果,并与工程实测值相比较,二者数值吻合较好。Based on an Engineering Example which was supported by the stepped soil-nail wail, a numerical analysis model was established by FLAC3D,and the process of the excavation and supporting was simulated, and the numerical results of the soil nails internal force and founda- tion pit deformation were obtained. The simulation result was consistent with the test results.
