摘要
本文采用有限元软件MIDAS/GTS对合肥地铁一号线某地铁站的深基坑工程的施工过程采用分段盖挖顺作法进行数值模拟分析,得出地连墙的偏移结果,并与实际的监测数据做对比。研究表明:地连墙的偏移成拱形,最大值一般出现在基坑中部,加倒撑可以减小地连墙的偏移,但影响范围较小。研究结果将对类似施工和设计提供重要参考作用。
The finite element software MIDAS/GTS is adopted to make a numerical simulation for the construction procedure of the deep foundation pit in Hefei metro Line 1 to get the diaphragm retaining walls deviation,and compared the results with the monitoring data .The result shows that the diaphragm retaining walls deviation presents to be arch, and the maximum generally occurred in the middle of the foundation pit,and adding transform support can reduce the diaphragm retaining walls deviation but the scope of influence is not too much. The results of t he study will provide important reference for similar construction and design.
