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 common geological problem in the reservoir impounding process. There often exists significant difference between the prediction and the actual collapse ranges. A new method,named as balanced alluvial accumulation approach,is proposed for the prediction of reservoir bank collapse on the basis of the surveying of bank collapse cases of more than 10 large reservoirs in China,the measurement on all kinds of stable angle of collapse phenomenon,and the analysis of the applicable conditions,the collapse mechanism and the collapse factors of the current prediction method of bank collapse. The new method has the reasonable initial points and prediction parameters and overcomes the deficiency of the traditional prediction method of bank collapse. It is also verified by a case study.
