| 摘 要： | 从弹性力学中圆筒受均布荷载的解出发，把圆形支护结构作为弹性地基梁，把圆形支护结构的拱效应作为支护结构的等效支撑作用在弹性地基梁上，从而得出了一个计算圆形支护结构内力和位移的拱效应等效支撑方法。工程实例的计算表明，该方法是实用而有效的。

| Abstract: | A method of equivalent retaining of arch effect for computing inner force and displacement of circular retaining structure is presented. An equivalent retaining structure of arch effect is got based on the solution of cylinder under uniform distributed loading in Mechanics of Elasticity and then this equivalent retaining structure is applied to an elastic foundation-beams to compute inner forces and displacements of the circular retaining structure. Engineering examples illustrate the feasibility and validity of this method. |

| Keywords: | circle retaining structure equivalent retaining of arch effect inner force and displacement |
