| 摘 要： | 针对现有基坑支护计算理论的缺点,运用FLAC3D对西安市某深基坑在无支护条件下的开挖过程进行了数值模拟,分析了基坑的变形和失稳机理,确定出基坑的破坏模式。据此,对原基坑支护方案进行优化,优化方案又用FLAC3D进行了模拟和现场实验验证。结果表明优化方案是可行的,同时也证实了FLAC3D可以用来对深基坑支护进行优化。

| Abstract: | In view of shortcoming of calculating theory of foundation pit support,FLAC3D was applied to simulate excavation of the deep foundation pit without retaining in Xi'an city.The deformation and failure mechanism of the foundation pit were analyzed and its fracture type was ascertained.The optimizing design scheme for the foundation pit was proposed basing on these results,which is also confirmed by FLAC3D.The results of on-site test proved that the scheme was feasible.At the same time,the results indicate that FLAC3D as a numerical simulation tool is suitable for optimizing design of foundation pit. |
