代尔夫特液压公司综合模型研究的结果是，在随机波浪攻击下，建立了碎石堆护岸和防波堤的新稳定性公式。这些公式包括波浪周期、风暴持续时间和结构渗透性等参数以及明确定义的损坏级别。 Hudson 型公式的主要缺点已得到解决。这些新配方的开发已在前面描述过；本文不再重复这一进展。给出了稳定性公式以及参数的可能应用范围。展示了如何在确定性设计和概率性设计中使用这些公式。确定性设计程序给出的曲线显示了各种参数的影响。概率设计产生的曲线显示了结构生命周期内超出损坏水平的概率。
New stability formulas for rubble mound revetments and breakwaters under random wave attack have been established as a result of a comprehensive model investigation at Delft Hydraulics. These formulas include parameters such as the wave period, storm duration, and permeability of the structure and a clearly defined damage level. Main shortcomings in Hudson‐type formulas have been solved. The development of these new formulas was described earlier; the present paper does not repeat this development. The stability formulas are given with the range of possible application of the parameters. It is shown how the formulas can be used in both deterministic and probabilistic design. The deterministic design procedure gives curves showing the influences of the various parameters. Probabilistic design results in curves showing the probability of exceedance of damage levels in the lifetime of the structure.
