Prediction of Reservoir Bank Collapse Based on the Limit Equilibrium Theory

The prediction of reservoir bank collapse width is a unique problem encountered in the construction hydropower projects. Existing empirical graphic methods are based on final state and can be used to predict only width, they thus do not adequately reflect characteristics process. To solve this problem, model for limit equilibrium theory was established, key parameters process were analyzed. results reveal necessity selecting reasonable underwater accumulation rate when predicting using theory. At constant ratio water depth slope height, increases with increasing linear relationship between them. In contrast, angle has little impact width. Specifically, it mainly affects first but effect subsequent collapses. With an increase angle, fluctuates rises. better explain time-dependent behavior collapse. research high significance loess
