防波堤的断面设计,主要取决于设计波浪要素。由于海浪出现的随机特性,因此一般都只能用它的统计特征值来表示。对于设计波浪的标准通常要规定:1、设计波浪的重现期(波浪的长期分布);2、设计波浪的波列累积频率(波浪的短期分布)。如交通部港口工 Breakwater section design, mainly depends on the design of wave elements. Due to the random nature of waves, they can only be expressed by their statistical eigenvalues. The criteria for the design of a wave usually require: 1, the design of wave recurrence (long-term distribution of the wave); 2, design wave wave accumulation frequency (short-wave distribution).
