黄土高原某水库黄土湿陷性问题分析及处理建议

Analysis of Loess Collapsibility in a Reservoir on the Loess Plateau and Treatment Suggestions

某水库位于黄土高原高山峡谷地带,场区地形狭窄,坝基岩性为土岩双层结构,上覆更新统黄土厚度大,而且具有自重湿陷性。本文根据场区地形地貌特点和试验资料对湿陷性黄土的湿陷性问题进行了分析,并提出了处理建议,为以后类似场区水利工程建设提供借鉴。

A reservoir is located in the high mountain valley of the Loess Plateau,the terrain of the site is narrow,the dam foundation is lithologic with a double layer of soil and rock,the overlying Pleistocene loess is thick,and has selfweight collapsibility.This paper analyzed the collapsibility of collapsible loess according to the topography and landform features of the site and the test data,and put forward treatment suggestions,which could provide reference for the future construction of water conservancy projects in similar sites.
