| 摘 要： | 利用ABAQUS有限元软件,分析相邻基坑在考虑渗流作用时开挖的相互作用及对周边环境的影响,并结合广州地铁三号线与六号线换乘站天河客运站地铁工程,建立平面模型进行系统分析,通过对比分析有无渗流作用时相邻基坑开挖的围护结构内力、变形及周边土体沉降,论证了考虑渗流对相邻基坑开挖分析的重要性。

| Abstract: | The adjacent foundation interaction and impact on surrounding environment in foundation excavation under considering seepage effect are analyzed with the ABAQUS large-scale finite element software in this paper. Taking the Tianhe passenger station of the Line 3 transfer Line 6 in Guangzhou for example,the plane model is established with the aid of ABAQUS,and the mutual influence and surrounding distortion of the adjacent foundation pit excavation in considering the seepage effect under the different operating step are systematic analyzed. Contrast to the force and distortion of the foundation structure and the surrounding stratum subsidence,the importance of the seepage effect in the neighboring foundation pit excavation analysis is proved. |
