Three-grade four-level division method-based reservoir bank collapse prediction method

The invention discloses a three-grade four-level division method-based reservoir bank collapse prediction method. The method comprises the steps of measuring a current topographic section of a bank slope; dividing geologic structure types of the bank slope and drawing a geological section map; determining a stable slope angle of the bank slope after reservoir filling; drawing a stable slope shapeof reservoir bank collapse prediction; determining relative slope angle grades; and determining bank collapse difficulty levels. The shortcomings of uncontrollable bank collapse prediction result andrelatively large bank collapse prediction width due to the fact that actual bank collapse width is often inconsistent with the prediction result and even is greatly different from the prediction result and excessive influence factors are considered in the prior art are overcome; and the method has the advantages of simplicity and easiness, strong operability, and accurate and reliable bank collapse prediction result. 本发明公开
