试验研究表明 ,不规则波对斜坡堤护脚棱体稳定性的威胁大于波高对应于Hs 的规则波 ,斜坡堤护面形式对护脚块石的稳定也有影响。Gerding公式虽然准确地描述了棱体在波浪作用下的稳定性规律 ,但由于护面糙率、透水率等因素的影响在工程上应用仍需进一步修正。文章指出在中低水位 ,Gerding公式计算的护脚棱体稳定重量有可能偏小 ,并给出了不同类型护面下护脚棱体稳定计算的修正系数
The experimental results show that the irregular wave poses a greater threat to the stability of slope leg embankment than the regular wave whose wave height corresponds to Hs. The shape of the slope embankment also has an impact on the stability of retaining leg rock. Although the Gerding equation accurately describes the stability of the prism under the action of waves, the application of the Gerding equation still needs further correction because of the influence of roughness and water permeability of the cladding. The article points out that in the middle and low water level, the stable weight of the retaining limbs calculated by the Gerding formula may be small, and the correction coefficient for the stable calculation of the retaining limb under different types of retaining surfaces is given
