The anti-sliding stability of the deep and shallow zone of gravity dam foundation in powerhouse section of Jin anqiao gravity dam,under combined effects of dam and powerhouse,was analyzed using the limit equilibrium and strength accumulation coefficient methods.

And the strength accumulation coefficient method is also adopted for investigation of damage model and safety checking.

The strength accumulation coefficient method based on partial coefficient of reliability theory is applied to Tingzikou hydropower project.

Application of strength reserve coefficient method of nonlinear finite element in stability analysis of arch dam

The authors apply strength reserve coefficient method and APDL technique to analyze the stress stability of CSG in static state.

Based on hydropower projects in Tingzikou,anti-sliding stability for the complicated foundation of gravity dams is analyzed by using non-linear FEM Computed by the strength reserve coefficient method,the gradual destruction process of dam foundations is obtained and the most dangerous sliding mode of system is discovered.

The dam final stability index is defined by the strength reserve coefficient in its limit equilibrium state.

Meanwhile,the influences of elastic modulus ratio of dam to foundation and stress distribution along foundation surface on the failure process and strength reserve coefficient(SRC) are studied.
