汕头港广澳港区防波堤顶高程计算及模型验证

防波堤顶高程是决定防波堤造价的主要因素之一。为有效控制投资,通过采用斜向浪折减、波浪爬高方法计算堤顶高程,并进行模型验证分析。得出在2 a一遇的波浪作用下,防波堤顶高程的降低对港内泊稳条件的影响很小。因此,在确定防波堤顶高程时应结合其功能特点、使用、防护要求,选择合适防波堤高程控制标准及计算方法,进而确定防波堤的顶高程。

Top elevation calculation and model validation of Shantou port Guang'ao port area breakwater

Breakwater top elevation is one of the main factors determining the breakwater cost. In order to control the investment, this paper calculates the top elevation and model validation using oblique wave reduction, and by wave run-up method. It is concluded that the reduction of the breakwater top elevation has little impact on the inner-harbor mooring conditions under 2-year frequency wave action. Therefore, to determine the breakwater top elevation, we shall consider its functional characteristics and utilization and protection requirements to select appropriate breakwater elevation control standards and calculation methods, and then determine the top elevation of the breakwater.
