| Abstract: | Seepage deformation is one of the important factors of dam stabilisation with wet storage of flyash. On the basis of three kinds of flyash in Qinling power plant and by the simulation of natural sedimentation flyash and compacted flyash, the seepage deformation test has been made in different dry densities. The test results are analyzed to obtain the relationship between impervious strength, types of seepage deformation and dry density of flyash, grain composition, test method, and also to obtain the machanism of seepage deformation of flyash in this paper. |
