本文通过模型试验对高基床防波堤顶墙前人工块体的防浪掩护作用进行了系统研究。根据总荷载(总水平力、总垂直力、总倾处力矩)的实测值,得到了无掩护的总荷载的变化关系曲线和不同掩护方式时掩护系数的经验计算式。本文的结论可供工程设计及港工规范修订时参考。 In this paper, a model test is conducted to study the effect of wave prevention on the artificial block before the breakwater wall of high bed. According to the measured values ​​of total load (total horizontal force, total vertical force and total declination moment), the change curves of total load without shield and the empirical formula of shield coefficient under different shield modes are obtained. The conclusions of this paper are available for reference when engineering design and Hong Kong workmanship specifications are revised.
