Research on Construction Technology of Clay Core Wall Filling for Rockfill Dam in Yundong Reservoir
Clay core wall is a central anti-seepage body of an earth rock dam made of cohesive soil material.It is commonly filled with materials such as clay and loam,and its permeability coefficient value is required to be less than 1/1 000 of the permeability coefficient of the dam shell material,and not more than 10 Lu.The working conditions of water conservancy engineering are complex,and it is difficult to accurately grasp natural conditions such as hydrology,geology,and meteorology during construction,which increases the difficulty of project construction.This paper elaborates on the construction technology of filling the core wall of a clay core wall rockfill dam,including the treatment of high natural moisture content precipitation,compaction tests of clay materials,construction technology of clay core walls,and key and difficult points of clay material filling.
