摘要： 针对安徽省芜湖市某场地深厚淤泥质土层的基坑围护工程，提出重力式水泥土墙圈椅式结构，首先对影响重力坝稳定性的因素进行分析，然后比选重力坝型式，最后通过优化分析得出围护结构的最佳截面，发现只有当加固体达到一定厚度且坝体的入土深度合理时才能保证基坑的稳定性。

Abstract: A soilcement mixed gravity retaining wall was used as the deep excavation supporting structure in Wuhu, Anhui Province. The project site consists of large thickness of peaty soil soils. Factors that affecting the stability of the gravity retaining walls are evaluated and the optimized dimensions of the gravity retaining wall supporting structure are obtained. It is observed that the gravity retaining wall supporting structure requires a minimum thickness as well as a minimum embedment depth.
