Abstract
This thesis examined the reproducing for realities of the residual pore water pressure which I analyzed residual behavior of groundwater of the reservoir limb landslide with drawdown of reservoir level, and worked out admeasurement technique to get residual rate of residual pore water pressure rationaly. Taking into account these rearities, I worked out permeability property of reservoir limb landslide in every geological feature by seepage flow analysis of converse calculation, and next, use this permeability property, I calculated residual rate of pore water pressure which met reservoir drawdown rapidity. In addition, I overwhelmed course of landslide and showed the residual rate which met reservoir drawdown rapidity, permeability of a lump of clay. We can set residual rate of residual pore water pressure to use for stability analysis by these disputation adequately.
