The unstabilization process of slope simulated by disturbing energy method

On the basis of non linear finite element analysis, the unstabilization process of slope was simulated by disturbing energy method in the thesis. Combined with some slope on the Yangtse River, the weak part and latent slide wedge are determined in different stage by non linear finite element analysis and disturbing energy method,thus the unstabilization process of slope is simulated. The calculated result agrees fairly with the measured result.
