Method for calculating side displacement of arc-shaped underground continuous wall

Provided is a method for calculating side displacement of an arc-shaped underground continuous wall. The method comprises the steps that the arc-shaped underground continuous wall is simplified as a cylindrical shell, a curvilinear coordinate system is established, the relationship between surface strain in the arc-shaped underground continuous wall and the displacement is established according to a classical shell theory, the relationship between stress of any point of the arc-shaped underground continuous wall and the displacement and a balance differential equation of any infinitesimal in the arc-shaped underground continuous wall are determined according to the Hooke's law, a balance differential equation of the arc-shaped underground continuous wall is deduced, and therefore the side displacement of the arc-shaped underground continuous wall is determined according to boundary conditions of corresponding working conditions. 种计算弧形地连墙侧位移的方法，所述方法通过将弧形地连墙简化为圆柱壳，建立曲线坐标系，根据经典壳体理论，建立弧形地连墙中面应变与位移之间的关系、根据胡克定律确定弧形
