| The limit equilibrium mechanics in analytical stability of slope has been accepted by many engineers, because its simply mechanical mode and analytical method can be easily used and has been validated in engineering practice. There have some no-rational hypothetic for this mechanism, so the computational mistake is larger than the observation. The theory system of the finite element method (FEM) is more integral than this traditional method by adding the constitutive relation of materials and the harmonious deformation condition. Therefore, FEM is affluent in the analytical theory for stability of slope, and the estimated precision of stability is been increased, and the strain and stress of slide can be explained roundly. Based on these virtues, the FEM has been widely used to analysis the stability of slope.The stability of dump is analyzed by ANSYS software, involved the process of modeling and selecting the constitutive relation of materials with respect to the geometry, boundary condition and geological condition of this dump. On the basis of analysis of stability of dump, the part and integrally static analysis of dump have been judged according to the solving method of the Bureau of Mines of U.S.A, and it give some proposes for its reclamation.At the same time, the dynamical analysis of slope is according to spectrum analysis and transient dynamic analysis for the 4 magnitude, and there is the reacting rule of mode and maximum dynamical value, and the laws of the acceleration, deformation, stress and strain of any mass point are been determined the nature. With respect to the academic analysis, the affecting factors of static and dynamic stability are advanced, and the advices of reclamation and letting project are proposed for this dump.. |
