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.
