摘要
受多种因素的综合影响,水库泥沙淤积表现为一个复杂的非线性动态过程,影响着水库的运行方式和其他效益的发挥。针对目前常用的几种计算水库泥沙冲淤量方法存在的问题,本文以三门峡水库为例,将支持向量机应用于水库泥沙冲淤量计算和预测。算例结果表明,该方法计算结果较为合理,计算过程涉及的参数较少,使用简便,适用于水库泥沙冲淤量的快速计算和预测。
Affected by a variety of factors,the sedimentation of the reservoir appears as a complex nonlinear dynamic process,which affects the operation mode and other benefits of the reservoir.Aiming at the problems existing in sever al commonly used methods for calculating reservoir erosion and deposition,this paper took Sanmenxia Reservoir as an example,and applied support vector machines to the calculation and prediction of reservoir erosion and deposi tion.The results of calculation examples show that the calculation results of this method are reasonable,the parame ters involved in the calculation process are relatively small,and the application is simple and convenient.It is suit able for the rapid calculation and prediction of sediment and erosion in the reservoir.
