一种悬臂式挡土墙的优化设计及应用研究

Study on Optimized Design and Application of a Cantilever Retaining Wall

该文以某市老路拓宽工程为背景,根据实际工程改进悬臂式挡土墙的结构设计,得出一种悬臂式挡土墙的优化设计—仰斜式悬臂挡土墙。通过对普通悬臂式挡土墙和仰斜式悬臂挡土墙的对比分析,得出在一定的工程条件下,仰斜式悬臂挡土墙在土压力、稳定性、地基承载力、材料经济性等方面有较大的优势,从而能为某些在具体情况下的挡土墙优化设计提供一定的参考。

The article describes the optimized design of a cantilever retaining wall-the inclined cantilever retaining wall based on an old road widening project of improving the structure design of cantilever retaining wall in a city. After the comparison and analysis of the common cantilever retaining wall and the inclined cantilever retaining wall, the inclined cantilever retaining wall is more superior in the earth pressure, stability, subgrade bearing capacity, material economy and etc. under a certain engineering condition so as to provide some references for the optimization design of retaining wall under the special conditions.
