摘　　要：根据上海地区具体工程实例,通过归一化得到了水泥土重力式围护结构墙体的水平位移函数表达式,然后采用最小势能原理,推导了上海地区水泥土重力式围护结构墙体水平位移的简化计算公式,并对影响墙体位移的若干因素进行了分析.采用该墙体位移简化公式对上海地区十个工程进行了计算,结果表明计算值与实测值之间的平均相对误差为13.5%,从而验证了该方法的适用性.The lateral displacement function of the gravity retaining wall was normalized through several excavations in Shanghai.The simplified formula of lateral deformation of gravity retaining wall was deduced through principle of minimum potential energy.Meanwhile,factors that affect deformation of gravity retaining wall were also analyzed.The simplified formula was adopted to calculate the lateral displacements of gravity retaining walls of ten excavations.The average relative error between the calculated results and the measured results is 13.5%,which proves that the method is suitable for calculating lateral displacement of gravity retaining wall.
