Analysis on formation mechanism and stability of deposits slope located above left dam abutment
摘要
Abstract
The problem of deposits slope is often encountered in constructions of hydropower projects in Southwest China. The study combines geology phenomena and drill core data, based on areal geology survey, rainfall data, and so on. The thought of engineering geology qualitative analysis is applied to study on the slope stability. On the basis of geological analysis, the deposits body has the feature of multi-stages and composite formation mechanism, and it is one of typical evolution models of the bank slope of Nujiang Great Canyon. The coupling effect mechanism of endogenic and exogenic geological processes of the deposits body is proposed. Aiming at spatial structure features and special location of deposits slope, the finite-difference and strength-reduction method is adopted to compute its stability factors under natural, rainstorm, seismic conditions. The above discussions offer reasonable evidence to constructions of the project and partial reinforcements of the slope and provide reference for stability analysis of similar deposits slopes in the river basins.关键词
