基于ABAQUS强度折减法某铀尾矿坝稳定性分析
The Analysis of a Uranium Tailings Dam Stability Based on ABAQUS Strength Reduction Method
摘要
Abstract
From the combination of the finite software of ABAQUS and strength reduction method,making full use of powerful post-processing ability of ABAQUS,this study analyzes a uranium tailings dam stability.The displacement mutation of slope feature control points and plastic zone breakthrough of slipping plane from the dam slope toe to top are used as a sym-bol of the whole slope instability.When plastic zone in the slope sliding surface is connected from the slope toe to top, plastic strain and displacement of characteristic control points result in mutation,the dam slope is in a critical state of sliding failure,while the strength re-duction factor is defined as the minimum safety coefficient of dam slope stability.Through an example of a uranium tailings dam stability analysis, it can predict accurately and vividly dam slope potential sliding surface position and evaluate the stability of dam slop,especially for the stability analysis of complex terrain slope,which is a simple and practicable method.关键词
