| 摘 要： | 针对紧邻深基坑工程设计案例进行其相互影响分析,采用有限元分析软件MIDAS/GTS模拟了紧邻深基坑在不同施工工况下基坑的相互影响。分析表明,两紧邻深基坑在不同的施工组合下同时施工会诱发对方基坑围护结构发生不同程度的水平侧向位移,其最大水平侧向位移均出现在开挖至基底的施工工况中。

| Abstract: | A project design adjacent to deep foundation pit was analyzed by using the finite element analysis software MIDAS/GTS,and the deep foundation pit construction in the different conditions was simulated.Based on the simulation results,the conclusion shows that when two adjacent deep foundation pits are constructed simultaneously in different conditions,the enclosure structure of another foundation pit will occur different horizontal displacement,and the maximum horizontal displacement of one foundation pit will appear when another foundation pit is excavated at the bottom. |

| Keywords: | foundation pit adjacent construction interaction double-row pile pre-anchorage cable displacement |
