摘　　要：越浪作用直接关系到直墙建筑物的安全、顶高程的决定等问题。采用物理模型试验,研究不规则波越浪压力在不同基床肩宽、基床高度、胸墙顶端相对静水面高度与波浪要素等因素影响下的规律。通过最小二乘法和非线性多元回归分析,拟合出无因次越浪压力和各主要影响因素相互关系的计算公式,供工程设计参考与进一步研究。The wave overtopping forces relate directly to the safety of vertical-wall structure and the decision of the top elevation and funds.Physical models are conducted to research the influential factors for irregular wave overtopping forces.The results show that the key factors are the foundation bed width,the foundation bed height,the height of the parapet to the still water surface,and wave parameters,etc.Based on the least squares method and the multi-varied nonlinear regression model,an empirical equation is fitted about the non-dimensional wave forces and its main influential factors,which may serve as a reference for the engineering design.
