摘要
针对深水斜坡堤堤脚块石的稳定性问题,通过二维物理模型试验进行研究。结果表明,深水斜坡堤堤脚块石的稳定性随相对水深h_t/h及破坏数N_(od)的变化规律同有限水深相比存在一些差异。为此,依据试验结果对可能影响深水斜坡堤堤脚块石稳定性的因素进行深入分析,然后将Van der Meer公式做了局部修正,该修正后的公式与试验结果的一致性较好,可供深水斜坡堤设计时参考。
Aiming at the toe rock stability of rubble mound breakwaters in deep water,we apply 2D physical models to research the problem.The results show that there are some differences between deep water situations and depth limited situations in the change rules of toe rock stability with relative water depth h t h and damage number N od.Based on the test results,we perform an in-deep analysis of factors that may affect the toe rock stability,and modify the Van der Meer formula.The revised Van der Meer formula is in good agreement with the test results,which can be used as reference for the design of rubble mound breakwater in deep water.
