摘要
由于近岸波浪动力受地形等主要因素的影响变化剧烈.尤其伴随着波浪破碎,增加了直墙上波浪力确定的困难。直墙上波浪力的确定在现阶段仍以物理模型试验为主。然而,不同的研究者所得的结果往往差异较大。文中通过物理模型试验,对直墙上波浪力计算中几个常见的问题进行了进一步的研究和探讨,提出同时刻压强沿水深的分布型式主要有局部冲击型、均匀分布型和过渡型三种。分析结果可为直墙波浪力更为准确的确定提供依据。
Determination of wave forces on a vertical wall is difficult owing to the violent change of near-shore wave dynamics by topographic and other factors and to subsequent wave breaking. At present, physical model tests are widely em ployed for determination of wave forces on a vertical wall. However, different researchers have obtained different results. In this paper, through physical model experiments, more investigation and discussion of some problems about wave forces on a vertical wall have been done. 'I his paper brings forward that the distribution of wave pressure along depth has three types: local impact type, uniform distribution type and transition type. Analysis results can provide foundation for truly deciding wave forces on a vertical wall.
