摘　　要：以奉节县三处典型滑坡体原位直剪试验为依据,分析了泡水前后碎石土抗剪强度及其与颗粒分布的关系;得出了碎石土的抗剪强度参数及其与碎石含量、含水量的关系;为类似滑坡治理和稳定分析提供试验依据及力学参数,以指导设计和施工。According to the in-situ shear test for three typical landslides in Fengjie County,the shear strength of gravel soil before and after immersion in water was analyzed,and its relationship with the grain distribution was also analyzed. The shear strength parameters of gravel soil were obtained and its relationship with the gravel content and water content was also obtained. The analysis provides experimental basis and mechanical parameters for the analysis of similar landslide treatment and stability,which guides the design and construction.
