如何确定近海水域中水工建筑物的顶标高是设计工程师必须考虑的重要问题。建筑物顶标高选取的是否合理主要取决于潮位和波高。相对地说潮位问题是容易解决的,而波浪特别是涉及到浅水波浪问题则是十分复杂的。目前,由于海浪理论包括规则波理论本身还不够完善,因此,根据某些理论获得的纯理论结果并不能作为设计水工建筑物的唯一依据。理想的办法是 How to determine the top elevation of hydraulic structures in offshore waters is an important issue that designers must consider. Whether the elevation of the top of a building is reasonable depends mainly on the tide level and wave height. Relatively speaking, the problem of tide level is easy to solve, and the wave is especially complicated when it comes to shallow water wave. At present, the purely theoretical results obtained from some theories can not be used as the sole basis for the design of hydraulic structures because the wave theory, including the regular wave theory itself, is not perfect enough. The ideal solution is
