摘要
Abstract
Slope stability is the key technology of slope prevention and control engineering.Slope stability is directly related to people's life and property safety.Based on the engineering background of a building slope in Yanji City,the physical and mechanical parameters of the slope are obtained by means of field investigation,drilling data,test analysis and numerical simulation.The stability of the slope is analyzed and evaluated by using FLAC3D software and Moore-Coulomb constitutive model.Two typical sections are selected to establish the model.The stress and the maximum unbalanced force of the slope under the influence of gravity are simulated and analyzed.The safety coefficients of the two sections are calculated,and cloud diagram of the X-direction stress and the Z-direction displacement,and the increment diagram of shear strain of each section are analyzed.Through comparison,the trend of slope displacement and stress change is obtained,and the area where the slope is prone to instability is determined and determinate whether the slope needs to be treated.In this paper,the stability calculation of a slope in Yanji is carried out,and the deformation and failure mechanism is probed,which provides a reference to the stability analysis and treatment design of similar projects.关键词
