摘　　要：随着天津地区经济的发展,超深基坑工程越来越多。这类工程多采用盖挖逆做的施工方法,多数采用地下连续墙作为地下支护结构。本文根据天津地区某处工程实例,就土压力和墙体侧移的关系进行研究,对各深度测点的现场监测数据和利用朗肯土压力理论得出的计算值进行比较,分析不同深度情况下各个测点土压力和墙体侧向变形的关系和单一测点在开挖深度不同的情况下土压力和墙体侧移的变化情况。With the economic development in Tianjin,the deep excavation works have become more and more.Most of them employ the top-down construction method,using the diaphragm walls as the supporting structures.According to the project which is in Tianjin,the monitoring data were compared with theoretical data so as to study the relationship between the lateral deformation of diaphragm walls and earth pressure.The relationship between lateral deformation of diaphragm walls and earth pressure in different depths and the changes of single-points would be found out.
