通过对南京某在建大型深基坑工程开挖过程中 T 形组合地下连续墙的分析，利用 ABAQUS 有限元软件建立 T 形组合地下连续墙开挖三维有限元模型。主要对墙体水平位移及墙顶、地表沉降和墙体应力进行模拟。同时对监测数据与模拟数据进行了分析。结论表明：现场监测数据和模拟数据吻合度较好，T 形组合地下连续墙增加整体抗弯能力，墙体结合处有应力集中现象。为类似地质条件下的 T 形组合地下连续墙开挖施工及监测提出相关建议。

The three-dimensional finite element model of the T-combined continuous concrete wall is built by using the fi-nite element software ABAQUS through the analysis of a large deep foundation pit ’s excavation process under construction in Nanjing .The surface settlement ,lateral wall displacement and wall stress are simulated and monitored mainly .At the same time ,the monitoring data are analyzed .The results show that the simulated data could coincide with the monitoring data ,the T-combined continuous concrete wall could increase the overall flexural capacity ,and the stress concentration phenomenon would appear in wall junction .The related construction and monitoring suggestions are put forward for the T-combined continuous concrete wall under similar geological conditions .
