摘要

通过二维物理模型试验,研究了相对波高、波陡、相对水深和直墙前斜坡块石棱体上扭王块体对水平式混合堤结构所受波浪力的影响规律。通过分析试验结果得出如下结论:直立结构各处所受波压强总体随相对波高和相对水深增大而变大;波陡对结构所受波压强的影响较小;直墙前斜坡块石棱体上的扭王块体能明显减小结构所受波浪力。通过试验值和各公式值比较可知,合田公式计算值与掩护良好的直墙受力情况相近,合田修正公式计算值能较好拟合挡浪墙的受力规律。拟合出规范修正公式计算没有被掩护直墙处的波压强。
        In this paper, through the 2 D physical model test, a research was made to analyze the influence factors for wave forces on horizontally composite breakwater including relative wave height, wave steepness, relative water depth and accropode on the rubble mound in front of the vertical wall. The result of the test show that: the wave pressure on the vertical structure generally increases with the increase of relative wave height and relative water depth, the wave steepness has less influence on the wave pressure, accropode can significantly reduce the wave force. Comparing test result and the different theoretical methods, the calculated value of Goda formula is similar to that of well-protected vertical wall, and the calculated value of Goda modified formula can better fit the force law of the wave wall. Standard modified formula is used to calculate wave forces on a place that is not covered.
