摘　　要：悬臂式挡墙凭借着厚度小、形式简单的优势在支挡工程中被广泛应用。但由于悬臂挡墙对基底压力要求高,设计参数难控制,当前悬臂式挡墙的结构性能仍然处于研究阶段。本文以传统悬臂式挡土墙为基础,设计了一种新型带卸压架悬臂挡墙来改善悬臂式挡土墙的力学性能,通过改变卸压架的位置与尺寸,找到了使悬臂挡墙性能达到最优的卸压架的位置和宽度,同时还研究了基底最大基底压力和最小基底压力的变化规律,研究成果可为相关工程提供参考。Cantilever retaining wall is widely used in retaining engineering with the advantages of small thickness and simple form.However,due to the high requirements of cantilever retaining wall on base pressure and difficult to control design parameters,the structural performance of cantilever retaining wall is still in the research stage.Based on the traditional cantilever retaining wall,this paper designs a new cantilever retaining wall with pressure relief frame to improve the mechanical properties of cantilever retaining wall.By changing the position and size of the pressure relief frame,the position and width of the pressure relief frame to optimize the performance of cantilever retaining wall are found.At the same time,the variation laws of the maximum base pressure and the minimum base pressure of the base are also studied.The research results can provide reference for related projects.
