| 摘 要： | 运用FLAC3D对南京市某住宅小区基坑工程进行了数值模拟分析,对基坑开挖和支护的力学稳定性进行了评价和预测,并对模拟结果与实测结果进行了对比,分析了基坑变形和失稳机理。据此,对原基坑设计方案提出了修正,修正方案又用FLAC3D 进行了模拟验证,表明修正方案是可行的。分析结果也证实了FLAC3D在基坑工程数值模拟方面具有良好的适应性。

| Abstract: | D-FLAC is applied to simulate and analyze the stability of the foundation pit for a dwelling house in Nanjing city. The mechanical stability for the excavation and retaining of the foundation pit is evaluated. The results from the simulation and analysis are compared with the monitoring results, and the mechanism of the deformation and failure of the foundation pit is also analyzed. Based on these results the amendment design scheme for the foundation pit is proposed, which is also confirmed by using 3D FLAC to prove the scheme is feasible for assuring the stability of the foundation pit. The results indicate that the 3D FLAC as a numerical simulation tool is suitable for the design of foundation pit. |
