摘　　要：针对等厚水泥土地下连续钢墙受力特性复杂的情况,介绍了水泥土地下连续钢墙截面构造、锁扣连接及竖向等强连接构造设计,并结合有限元计算采用三维“m”法进行水泥土地下连续钢墙承载变形特性分析。锁扣连接合理的摩擦刚度约束作用模拟,较为准确地实现了水泥土地下连续钢墙的受力状态计算。相关研究结论可为今后类似工程提供借鉴。Aiming at the complex mechanical characteristics of steel diaphragm wall under equal thickness cement soil,the design of section structure,lock buckled connection and vertical equal strength connection structure of steel diaphragm wall under equal thickness cement soil is introduced.Combined with finite element calculation,the bearing deformation characteristics of steel diaphragm wall under the cement soil are analyzed by 3D"m"method.The simulation of the restraint effect of the reasonable friction stiffness of the lock buckled connection can accurately calculate the stress state of the steel diaphragm wall under the cement soil.The relevant research conclusions can provide reference for similar projects in the future.
