扶壁式及L式挡土墙的模型土压力试验

Research on Calculating Methods of Soil Pressures on Counterfort Walls and L-Shaped Walls

汇总分析了扶壁式墙和Ｌ型墙等多种结构模型，在填干砂、湿砂、砂中灌水、水中填砂等不同条件下进行试验，得到扶壁式墙立板和底板土压力减少的分布规律，提出了比较合理的土压力近似计算公式和简易的计算图式。

The results of various structural model tests of counterfort walls and L-shaped walls under different soil filling conditions, such as dry sand, wet sand, sand filled with water, and sand under water is analysed in this paper. The decrease regularity of the soil pressures on the vertical walls and bottom slabs of the counterfort walls has been found as well as some rational approximate formulas and simplified charts about soil pressure calculation have been set up. Numerical example of an engineering project with analysis is given in the paper.
