水库塌岸是水库蓄水过程中经常遇见的水库地质问题,水库蓄水后水库实际塌岸与传统方法预测相比往往存在较大差异,通过对国内已建成的10多座大型水库的塌岸实例调查,分析已有塌岸预测方法的适用条件、塌岸机制和塌岸影响因素,提出水库塌岸预测新方法——冲堆平衡法,研究结果表明,冲堆平衡法克服了传统塌岸预测方法的不足,起算点和塌岸预测参数的确定更为合理,从理论上讲更接近于实际情况,并通过实例验证,该方法具有一定的推广和应用价值。
The reservoir bank collapse is a reservoir geological problem frequently encountered in the process of reservoir water storage. Actual reservoir bank collapse after reservoir impoundment is quite different from the traditional method prediction. Through the analysis of the bank collapse of over 10 large reservoirs in China, A case study was carried out to analyze the applicable conditions of the bank collapse prediction method, the bank collapse mechanism and the factors that affected bank collapse, and put forward a new method of reservoir bank collapse prediction - heap balance method. The research results show that the heap balance method overcomes the traditional bank collapse The prediction method is not enough, the starting point and the prediction of bank collapse prediction parameters are more reasonable, in theory, it is closer to the actual situation, and the example has proved that the method has certain promotion and application value.
