Application of plastics membrance at the dam slope to antifreezing heaving damages;

Protecting ice hazards methods of the dam slope use diverting slip in Longfenshan Reservoir;

Stability analysis on dam slope in Liaowan reservoir;

The mountain landslide dam is a common geological disasters,in the event of strong earthquakes,landslides dam formation of the large number of lakes of them,a large scale of it.

Using the principle of elastic dynamics of rock and the variational method of elastic mechanics, the dynamic mechanism is explored of landslide damming by shock wave when the landslide mass is sharply disintegrated and collides with high moving speed.

A landslide dam located in the Huanghe upriver was formed by two landslides,then formed the barrier lake which is core area of national natural protection now.

Seepage and its effect on dam slope stability in Wuling Hydraulic project;

Water level in small flood control in combination with irrigotion reservoir changes frequently,especially during irrigation period,the reservoir water level drops significantly,which would affect the dam slope stability.

Based on the dam slope stability calculation conducted for a high core wall type rockfill dam with linear strength index and nonlinear strength index respectively,the authors discuss the difference of the calculation results.
