摘要
近年来,人们对胸墙波浪力问题一直比较关注。本文收集了国内外12项工程共43组实验成果,对有关斜坡堤顶胸墙波浪力的计算方法进行了验证和比较。结果表明:用河海大学新提出的计算方法得出的数据并不比用《海港水文》计算方法得出的数据更符合实验情况,而渔港规范的计算值则明显偏大。对于胸墙前掩护效果不低于《防波堤》规范所要求的情况,胸墙波浪力(测压力和浮托力)乘以0.6的折减系数是合理的。
In recent years, people pay close attention to the wave forces on the parapet wall on rubble mound breakwaters. Experimental results from twelve projects at home and abroad were summarized in this paper. The relevant methods for calculating the wave forces on the parapet wall on rubble mound breakwaters were tested and compared. It was found that the values by the method proposed by HEHAI University didn't agree so well with the experimental results as that by 'Port Engineering Code' did. The calculating values by 'Fishing Prot Engineering Code' was evidently overestimated comparing with the experimental results. If the parapet walls protected with armor units as specified in the 'Breakwater Code', it will be reasonable to reduced the wave forces (both Horizontal and vertical) by a factor of 0.6.
