Experimental study on the force of parapet of sloping breakwater with accropode armor blocks under different slopes

综合考虑堤型结构参数和水动力因素,开展扭王字块斜坡堤不同坡度下胸墙受力的物理模型试验,探讨坡度、相对堤顶超高、相对胸墙高度、相对坡肩宽度、波陡、相对水深和相对块体尺寸等对扭王字块护面斜坡堤胸墙所受波浪力影响的变化规律,并通过多元回归非线性拟合法,总结出扭王字块体斜波堤胸墙水平波浪力的计算关系式。验证表明,该计算公式有良好的精确性。研究成果对防波堤工程设计具有重要参考价值。

Considering the structural parameters and hydrodynamic factors of breakwater, the physical model tests of wave force on breast wall of slope embankment with accropode blocks under different slopes were carried out, and the variation laws of wave force on breast wall of slope embankment with accropode blocks were discussed with the influence factors including slope, relative embankment top superelevation, relative breast wall height, relative slope shoulder width, wave steepness, relative water depth and relative block size, and using the method of multiple regression and nonlinear fitting, the calculation formula of horizontal wave force on breast wall of slope embankment with accropode blocks was summarized. The verification result shows that the calculation formula has good accuracy. The research results have important reference significance for the engineering design of breakwater.
