成层土中悬臂式地下墙内力计算等等值梁法

建筑基坑范围内的土层以成层土居多，基坑技术规范要求计算成层土的土压力时应分层计算，本文按等值梁法原理，给出了成层土中分层计算土压力，再计算悬臂式地下连续墙支护结构内力（剪力和弯矩）的方法。

Internal force calculating isobeam method of cantilever type underground wall in layered soil

Most Soil in the building foundation pit scope are layered soil, so the technical standard of foundation pit required that soil pressure of layered soil ought to calculate layer by layer. The paper based on the principle of isobeam method, has submited the methods to calculate soil pressure layer by layer and further to calculate prop structural internal force of cantilever type underground continuous wall.
