Study on stability of dispatching operation level of jiping channel in south — North water transfer project

The domestic and foreign research on the water level change of the channel scheduling involves many aspects at present. The water level fluctuation has an imortant influence on slope stability. In the process of water level fluctuation, the change of soil state from unsaturated to saturated and other problems which should be taken into account in the analysis of slope stability. A typical slope in the south to North Water Diversion Project is calculated by software in this paper. This paper described the simulation of the standard deviation of Mohr — Kulun, and mades a quantitative analysis of the influence of water level change on slope stability. The displacement and safety factor of the slope is obtained after the water level decline. It is of great significance for the design of water level control of all kinds of large-scale water transfer projects in our country.
