在海洋工程、水利工程等建筑工程中,合理地确定多年一遇波高、洪水量等,对于建筑物设计的安全和造价问题是十分重要的。兼顾安全和费用两方面的要求,就得在各种各样的计算方法中选择较为理想的方法进行推算。就海浪波高设计而言,较为普遍采用的方法是对年最大波高组成的系列,选取一条适合的理论频率曲线(如P-Ⅲ型曲线, In marine engineering, water conservancy projects and other construction projects, it is very important for the safety and cost of building design to reasonably determine the wave height and flood volume in many years. Taking into account both safety and cost requirements, you have to choose among a wide range of calculation methods the more ideal way to calculate. For wave height design, the more commonly used method is to select a suitable theoretical frequency curve (such as P-Ⅲ type curve,
