Research Abstract |
The stability analysis of the slope is a redundant problem. To statically determinate, within the frame work of limit equilibrium methods of stability analysis, no restriction need be placed at the outset upon the shape of the possible slip surface. It is necessary. The repetition calculation are necessary to get the results. This analysis is assumed the inner stress tau_r, tau_y change according to linearly equation which are satisfied the boundary condition. The principal stress sigma_1, sigma_2 and the shear stress tau are divided form tau_1 and tau_1. From the sigma_1, the shear resistance tau_f are introduced by the sigma1 tan phi. The instability zone are divided by tau > tau_f. The analysis results are checked by the experimental observation data. The analysis results conform well to the observation results.
