挡土拱圈的内力和变形计算

Computation of Inner Force and Deformation of Arch Retaining Structure

本文提出一个计算挡土拱圈内力和位移的非线性共同作用方法。工程实例的计算表明，该法是实用而有效的，为得到合理的挡土拱圈结构形式提供了有力的计算手段。

This paper presents a nonlinear interaction method for computing inner force and displacement of arch retaining structure. Engineering examples illustrates the feasibility and validity of this method. It provides a valid computation method for getting reasonable form of arch retaining structure.
