笔者曾于1981年进行了坡度为3％底坡上浅水破碎波对孤立圆柱作用力的实验研究,测定了不同波浪要素和圆柱直径下的破波总力。结果表明,影响圆柱破波力的主要因素是入射波陡和相对柱径,由此归纳了实验条件下破波总力与这两个因素的经验关系。由于条件限制,当时未能进行桩柱破波力垂直分布的试验。本文介绍这一补充试验的成果,并对破波力的构成特性进行初步分析。
In 1981, the author conducted an experimental study on the forces acting on the isolated cylinder by the shallow water breaking waves on the slope of 3% on the slope, and determined the total breaking force under different wave elements and cylinder diameters. The results show that the main factors that influence the breaking force of the cylinder are the incident wave steepness and the relative column diameter, and the empirical relationship between the total breaking force and the two factors under the experimental conditions is summarized. Due to the limited conditions, the vertical distribution of the pile breaking force was not able to be tested at that time. This article describes the results of this complementary experiment and a preliminary analysis of the compositional characteristics of the breaking force.
