中外港口规范对比研究Ⅲ:防浪结构护面块体稳定性计算标准

Comparison of domestic and foreigan port standard Part III:wave structure and selection standard of stability coefficient of armour block

文章对中国、日本、英国、美国等国内外港口相关规范中涉及的防浪结构进行了简要对比,并以典型的防浪结构-斜坡堤为例,重点对比分析了中外规范中对护面块体稳定性计算标准的差异。对比结果发现:中国规范在计算护面块体稳定性时对于稳定系数的选取要大于国外规范,采用国外标准计算的块体稳定重量普遍要比国内大;此外对比分析了国内外规范中对块体稳定性的计算公式后发现,国外规范中对于护面块体稳定性计算时考虑的因素较为全面,其适用条件更为明确,这将为涉外工程相关设计提供借鉴与参考。

A brief comparison of the wave protection structures involved in the relevant domestic and foreign port codes in China,Japan,Britain,and the United States were given in this paper.Taking sloping breakwater as an example,this paper focuses on the comparative analysis of the armor blocks in the Chinese and foreign codes about stability calculation standards.The comparison analysis results show that the selection of the stability coefficient of Chinese codes in calculating the stability of the armor block is larger than that of the foreign codes.The stability weight of the blocks calculated by the foreign standards is generally larger than that of the domestic ones;After calculating the stability of the breakwater it is found that the factors considered in the calculation of the stability of the armor block in the foreign codes are more comprehensive,and the applicable conditions are more clear.Which will provide reference and reference for the relevant design of foreign-related projects.
