Abstract
As a kind of layered rock slope, the bedding rock slope is the slope that the direction and the tendency of the layers and the slope is the same. The bedding rock slope landslide occurs easily. Rainfall infiltration has great influence on the slope stability. Along with the changes caused by global warming climate, annual rainfall increasing year by year, the frequency of the landslide presents the trend of increasing every year. Therefore, it has very important realistic meanings to study the stability of the bedding slope under seepage condition.
In this thesis, the stability of the bedding rock slope is studied with the method of numerical of all, all kinds of the analysis methods of slope stability currently are given, of which the realization of strength reduction FEM is emphatically introduced. The structural plane is analyzed from the angle of mechanics. And the condition of the landslide occurs along the structural plane and the largest slope height to keep the slope stability are , the calculation of the finite element method of 2-D seepage is obtained, and the coupling analysis of the seepage field and the stress field is , based on the actual engineering conditions, the finite element analysis model of the bedding rock slope is set up, the strength reduction finite element method and ABAQUS is used to analyze the stability of the bedding rock slope and the slope stress and the slope deformation of the critical , keeping other conditions the same, the slope stability under the conditions of different dip angles, thickness of layers, rainfall intensities, coefficients of permeability are analyzed pared to the slope stability under no seepage, and the influences of those factors on the bedding rock slope are studied.
Key words: bedding slope; seepage; stability; Finite Element Method; Strength Reduction Principle
