Critical slip field of slope in process of reservoir water level fluctuations

The process of reservoir water level fluctuation will cause the changes of the slope body in the pore water pressure distribution, which has influences on slope stability. By improving critical slip field of slope, the numerical simulation method of critical slip field of slope, considering the process of water level changes, is proposed. Thus, slope local safety factor and slope safety factor of the whole in the process of changes in water level course are calculated conveniently and rapidly. By means of stability analysis of a typical slope in the process of rise and fall in water level and comparing with other methods., the results show that the critical slip field method can search for any shape of the most dangerous slip surface; and the safety factor is reasonable.
