| 城市地铁车站基坑施工对周围环境产生较大影响，往往造成严重后果。本文采用数值计算和监测数据分析的方法对合肥地铁明光路基坑开挖过程中的地下连续墙墙体深层水平位移的进行分析，并将两种方法获得的结果进行对比分析，得出结论表明：在基坑开挖过程中地连墙水平位移呈现中间大、两头小的弓肚形态，最而大位移点随基坑开挖深度加大而逐渐下降，大致位于基坑深度三分之一到三分之二范围处；地连墙水平位移增量与开挖深度程正比，与土层的性质也直接影响到支护体的变形。该结果将对合肥市地铁车站基坑支护结构设计提供重要的借鉴作用。 |

| The subway station foundation pit construction has a great influence on the surrounding environment,cuasing serious influence. In this paper, the method of numerical calculation and analysisof the monitoring data have been adopted to make an analysis deep horizontal displacement of underground continuous wall in excavation process foundation pit in Hefei subway Mingguang Road. The results obtained by the two methods were compared and analyzed, and the results show that horizontal displacement of the diaphragm wall during the excavation of foundation pit present a bow belly shape that is the middle is big,both sides are small. The displacement point of the excavation is gradually decreased with the increase of excavation depth,located roughly between one-third and two-thirds of foundation pit depth range .Conjoined wall horizontal displacement increment is directly proportional to the excavation depth range .The soil property also affects deformation of the support system .The results will provide important referencefor the design of hefei city subway station foundation pit supporting structure |
