墙后填土对悬臂式挡土墙应力位移影响

Effects of the Stress and Displacement of Cantilever Retaining Wall with Different Backfill

为研究悬臂式挡土墙在不同墙后填料下的应力以及位移情况,对某悬臂式挡土墙建立有限元模型进行分析,得到其在砂土和粘土两种墙后填土的工况下的应力位移云图,根据有限元分析结果可以得到墙后填料使用砂土效果要弱于粘土,越靠近挡土墙顶端两者应力位移值相差幅度越大的结论.所得到的结论可以为边坡支护工程的设计以及研究提供相关的依据.

For the study of stress and displacement of cantilever retaining wall with different fillers after the wall, a cantile- ver retaining wall conducted by finite element model is analyzed, and the stress and displacement nephograms in sandy or clay fillers after the wall are also analyzed. According to the finite element analysis results, conclusion can be obtained that clay soil is better than sandy soil as fillers after the wall, closer to the top of the retaining wall displacement and stress value is bigger. The results can provide the basis for the design of slope supporting engineering and research.
