| 摘 要： | 以塑性极限分析理论为基础,将附加粘聚力理论运用于加筋土挡墙的极限分析,探讨了当土体处于主动极限状态、顶部一定深度范围内存在平行于墙面的张拉裂缝时,加筋土挡墙破裂面形式及其破坏时的临界高度,并引用了国外离心模型试验数据加以验证,结果表明本文解更接近于真实破坏情况,且适用于不同内摩擦角的加筋土体破坏.

| Abstract: | The additional-cohesion theory is used in the limit analysis of reinforced soil retaining wall based on plastic limit analysis theory.The tensioned crack parallel to wall face in definite depth is considered to research the rupture surface and critical height of the reinforced retaining wall.The result is validated by the data of centrifuge model test;and it is much close to the practical condition;it also suits the breakage of reinforced soil with different inner friction angles. |
