海堤工程设计规范上的越浪量公式是现在水工计算中广泛使用的计算越浪量的模型公式,其参数的取值是计算分析的重要内容,运用实测资料采用反分析法可以有效的确定模型参数。采用模糊数学法建立越浪量无量纲公式,并通过计算各参数变化对上海地区斜坡堤越浪量值的改变,计算结果表明:影响越浪量的主要参数是与波陡相关的无量纲参数,与相对墙顶高程相关的指数,波浪入射角度等参数,其中尤其以与波陡相关的无量纲参数对计算结果影响较大,这为反分析参数的选择提供了依据。
The formulas for calculating the overwreck of the seawall engineering design code are the formula formulas for calculating the overtopping current which are widely used in hydraulic calculation at present. The values of the parameters are important contents of the calculation and analysis. The use of the measured data can be effective Determine the model parameters. Using the fuzzy mathematics method to establish the non-dimensional formula of the overtopping quantity and calculating the change of the overwhelming value of the slope on the slope in Shanghai by calculating the variation of each parameter, the calculation results show that the main parameters affecting the overtopping quantity are the dimensionless parameters , The index related to the relative height of the wall, the angle of wave incidence and other parameters. Especially, the non-dimensional parameters related to the wave steepness greatly influence the calculation results, which provides the basis for the choice of inverse analysis parameters.
