Stability Generalized Analysis of a Large-Scale Accumulation Body Slope

Abstract:

A large-scale accumulation body, lying in left bank of a hydropower station dam, its stability is directly related to dam construction and operation. By means of engineering geological investigation on geological characteristics and geneses of accumulation body, the result shows the accumulation body is generally stable. Then, safety factor of accumulation body under different working conditions are calculated separately according to the method of EMU, The result shows that side slope is wholly stable and it can meet the stability requirements while the stability of section Ⅲ needs more studies. 3D model is built and applying FLAC program on stability of accumulation body under diverse conditions, it also shows that the whole stability of accumulation body is in a comparatively good condition. However, the possibility of partial slide still exists, and for this reason corresponding protections and reinforcements are proposed at last.
