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.

At present,it is not perfect to analyze the slope stability of rockfill dam only using traditional safety factors method.

It is indicated by calculation of seepage flow and analysis of slope stability that the tailing pond can meet the environmental protection requirement after the control and reinforcing measures are taken in design.

In addition the influences of nonlinear strength parameters φ0 and Δφ on slope stability were researched.

Analysis on the reliability of the arch dam abutment stability based on stochastic finite element;

In Connection with three dimensional geomechanical model testing for Shapai RCC arch dam abutment stability study,this paper mainly analyses the differences & similarities between the test results of the synthetical method & overloading method as well as applicability of these test results.

Combined with the three dimensions geological mechanics model experiment of the abutment stability of Sichuan Shapai RCC arch dam, the differences and similarities between the test results of Synthetical Measure and Over-loading as well as the possibility of application there of were emphatically analycised in the article.
