Research On The Back Analysis Of Elastic-plasticity Parameters And The Slope Stability

The back analysis of elastic-plasticity parameters is studied in software ANSYS by APDL. By reading the stress of the slope which brings by the gravitation avoids the first displacement. The method of the simulation of the excavation slope is the using of"the life and death"element. We can get the same result as the analysis of the locale.The analysis of slope stability by using strength reduction FEM in software ANSYS .The safe coefficient and the glide of the slope is base on the judge criterion of the development of the plasticity area. Some measures to improve the precision are put forward. The achievements include the infection to calculate precision by different mesh size of the slope and the boundary condition. At the same time the influence of different criterion to the safe coefficient is done. The crack slope is simulated by contact element to analysis the stability of the slope. The rule of obstruction to the distributing of stress and strain of the slope is influenced by different number of the cranny.The right bank of the reservoir is simulated, and the distribution of the stress and stain of the reservoir is discovered. The stability of the slope is analyzed.
