Determination of Partial Factors of Breast Wall on Top of Sloping Breakwater

By applying the theory of structural reliability, reliability analyses for the stability of a breast wall on the top of a sloping breakwater are carried out. Based on the analyses, the method for determining partial action / load factors and partial resistance factors of breast walls is expounded, and the design expressions with partial factors are given. The values of partial action / load factors and partial resistance factors are recommended preliminarily according to the computation for breast walls with typical cross-sections.

不同坡度下扭王字块斜坡堤胸墙受力的试验研究

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。
