【摘要】 在海岸工程(海堤,护岸)的设计中,越浪量是一项重要的控制条件,直接决定我们设计堤顶的高度。越浪量是指波浪作用在海堤上水体上爬后越过堤顶的水量,现今在几十年的研究基础下,国内外对于越浪量计算公式提出了多种建议方法。由于这些方法与公式大多是在室内水工实验室中,根据物理模型试验的结果提出的,对于实际问题,各种计算方法考虑的影响因素不尽相同,所以各个越浪公式的形式和参数存在较大差异,导致计算得到的越浪量存在误差。比如在特定的地区,特定的地形,在考虑风的作用下,观测得到的数据与现有的越浪计算公式所得结果存在较大不符合的地方。所以需要对我们测量的数据进行校核和分析。收集了英国、荷兰等国及我国的越浪量计算方法。大部分的越浪公式是根据数值模拟分析与物理模型实验所得,各个公式间存在较大的针对性与局限性。所以运用这些不同公式计算所得到的结果也存在较大差异。在长江口越浪量观测数据的基础上,首先对于各个越浪公式进行运算,并与实测得到的数据进行统计比较。然后分析各个越浪公式的敏感要素,推求其特点。最后对于长江口地区的越浪实际情况进行分析,判断各个公式在长江口地区的适用性与局限性。更多还原

【Abstract】 Coastal Engineering(seawalls,revetments) design,overtopping is an important control conditions,directly determine the height of our design dike.Overtopping wave action refers to the body after climbing over the seawall,Sheung Shui water dike,now in the research base for decades,the domestic and the overtopping formulas put forward a number of recommendations methods.Because these methods and formulas are mostly indoors hydraulic laboratory in accordance with the results of the physical model tests proposed for practical problems,various factors considered in the calculation method is different,so each overtopping formulas and parameters exist in the form of quite different,resulting in overtopping the calculated error exists.For example,in a particular region,a particular terrain,in consideration of the effect of wind,observation data obtained with the existing computing overtopping there is a big place does not meet the formula for the results.So we need to be checked and measured data analysis.For the Yangtze Delta region of the formula overtopping performed sensitivity analysis and comparison of factors is very important.This collection of the United Kingdom,the Netherlands and other countries and China’s overtopping calculation.Most formulas are obtained overtopping analysis and physical model experiments,between the various formulas targeted and there is a big limitation based on numerical simulations.Therefore,the results of these calculations using different formulas obtained are quite different.In this paper,in the estuary of the original Ding Liang(3) conducted overtopping on the basis of observational data,the first for each overtopping formula for computing,and the measured data obtained for statistical comparisons.Then analyze the sensitive elements of the various overtopping formulas,Deriving its features.Finally,the actual situation for overtopping Yangtze Delta region were analyzed to determine the various formulas in the estuary area of the applicability and limitations.更多还原
