| 摘 要： | 应用弹塑性大变形理论及有限差分理论,对地下连续墙加内支撑与地下连续墙加锚杆两种支护形式下基坑开挖引起的近邻建筑物沉降进行了模拟分析,分析表明:内支撑与土层预应力锚杆可有效减小基坑支护结构及近邻建筑物的沉降变形,而内支撑在控制基坑变形方面的作用要远大于土层预应力锚杆。

| Abstract: | The author applies elastic-plasticity large deformation theory and finite difference theory to analyze the sedimentation deformation of nearby building created by excavation of foundation pit supported with continuous wall-inside strut and continuous wall-anchor, recognizes that inside strut and soil anchor can decrease the sedimentation deformation of supporting structure of foundation pit and nearby building effectively, and the ability of inside strut to control deformation of foundation pit is more than soil anchor. |

| Keywords: | foundation pit building sedimentation deformation numerical modeling model |
