| 摘 要： | 以某工程为研究背景，通过二维和三维数值模拟，分析了人工挖孔桩的施工过程对紧邻基坑围护结构的影响，并根据计算结果对其进行专项设计.结果表明：人工挖孔桩施工过程中的空间拱效应明显；在直径3.0 m的挖孔桩距离围护结构约5.0 m的情况下，仅需采取简单的设计措施，即可保证围护结构的安全性.

| Abstract: | Based on an engineering case,2D and 3D finite-element tools were employed to analyze the mutual impact of constructing hand-dug piles close to retaining wall.Combined with the analysis data,some measures were implemented.The results show that the hand-dug piles have obvious space arch effect.When the net distance between 3 meter diameter hand-dug piles and retaining wall is 5 meters,only simple design measures are needed to ensure the safety of the foundation pit. |
