| 摘 要： | 在斜向波浪作用下,防波堤结构衔接段会产生波能集中、壅水和漩涡等复杂的水动力情况,对该区域块体稳定性和沉箱结构产生极不利的影响,本文开展了三维整体波浪物理试验研究,以揭示不同角度斜向波与块体稳定性和沉箱结构受力敏感性的关系。同时将得到的试验结果与规范公式计算结果进行比较分析,得出两者之间的差异性。试验结果可为工程设计中结构安全系数取值提供技术支撑,也可为将来相关规程或规范关于块体稳定重量和直立结构受力计算式的修订完善提供基础数据。

| Abstract: | Under the action of oblique waves, complex hydrodynamic conditions, such as wave energy concentration, backwater and vortex will occur in the junction section of breakwater structure, which may cause adverse impact on the stability of the block and the wave force on the caisson structure. In this paper, a three-dimensional integral wave physical experiment is carried out to reveal the influence of oblique waves from different angles on the stability of the block and on the caisson structure stress sensitivity. At the same time, the experiment results and the standard formula calculation are compared and analyzed to derive their differences. The experiment results can provide technical support for engineering design in the value of structural safety factor, and also provide basic data for the revision and improvement of the calculation formula of block stability weight and vertical structure stress in future codes or specifications |
