【摘要】 为研究尼山水库天然铺盖塌陷的原因和破坏机理,对塌陷区进行跟踪开挖,在查明地层结构及破坏过程的基础上,进行试验分析。依据现场实际渗流破坏条件,采用有代表性较大试件的天然原状土样和重塑土样, 在自行设计改装的渗透变形仪上,进行不同结构土体和渗流条件的渗透变形试验,能真实地反映铺盖土的渗流特性和破坏机理。更多还原

【Abstract】 In order to study the reasons of collapse and failure mechanism of the rude blankets, we carried on tracking excavation process on the collapse areas, and carried out experimenting and analysis on the basis of finding out layer structure and failure process. According as failure conditions of the field true seepage, the representative bigger undisturbed and remolded samples were chosen. The experiments of seepage deformation of the different structural soils and the different seepage conditions were done on the seepage deformation instrument which was designed and refitted by ourselves. The experimental results could truly reflect the characteristics of seepage and the failure mechanism of the blankets.更多还原
