摘要
在塑性极限分析理论的基础上,结合成拱效应提出了短刚性挡土墙后土体的破坏模式,导出了作用在其上土压力的上限值,并通过例子进行了计算;另外,也对柔性挡土墙在设计计算中存在的问题进行了论述.
Based on the soil plasticity and limit analysis and with the arching effect taken into consideration,the failure mode of soil mass of short rigid retaining walls is presented and the upper value of soil pressure is deduced.In addition,some problems in design calculation for flexible bulkheads are discussed in this paper.
