金沙江某电站利用滑坡碎(砾)石土作为防渗土料的试验研究

金沙江下游某电站防渗土料稀缺。在大范围土料调查的基础上,选定大村滑坡堆积物作为防渗土料开展地质勘察。在综合山地勘探、试验、物探、观测等资料的基础上,对土料的粘粒含量、砾(碎)石占量、天然含水量进行宏观分析和试验研究,并将土料在垂直方向上可分为Ⅰ、Ⅱ两个带。认为其粘性砾(碎)石土质量符合防渗土料、高塑性粘土的规范要求,储量满足设计需要。

TEST RESEARCH OF USING LANDSLIDE DETRITUS AND GRAVEL EARTH AS ONE HYDROELECTRIC STATION'S ANTI-SEEPAGE MATERIAL ON JINSHAJIANG RIVER

One hydroelectric station is lacking in anti-seepage on downstream of Jinshajiang River. On the basis of investigating on anti-seepage material, we take Dacun landslide deposit as an example, which will be treated as anti-seepage material habitat in geological prospect. According to integrative data on exploration, experiment, physical prospecting, observation, the macro analysis will be carried on, in which the earth borrow's clay content, the gravel and detritus content, the natural water content will be researched. The earth material will be divided into two sections that are I and II in the vertical direction. The result is that the quality of viscous detritus and gravel earth measure up the anti-seepage material and high plastic clay, and its reserves meets the design needs.
