| 摘 要： | 崩滑堰塞湖沉积物(层)是在特定地质环境下形成的第四系堆积层。5.12地震在四川形成了大量的堰塞湖,随着时间推移会形成堰塞湖沉积物,在水利水电工程建设中如何利用这些沉积物,需研究其工程地质特性和工程地质问题。以四川丹巴县关州水电站为例,在对河床闸坝堰塞湖沉积物形成机制研究基础上,对堰塞沉积物的分层、物理特性、压缩、抗剪及承载力等工程特性进行研究;最后对利用堰塞沉积物作为闸坝地基面临的主要工程地质问题进行了分析。

| Abstract: | The Ms 8.0 Wenchuan Earthquake on May 12, 2008 resulted in many dammed lakes where the Quaternary deposits are formed. This paper deals with such engineering geological characteristics as physical properties, shear resistance and bearing capacity and so on of these deposits, exemplified by the Guanzhou Hydropower Station in Danba. An approach to engineering geological problems of the dammed lake deposits as dame foundation is made. |
