在不规则波中对并排布置和串联布置的两个桩的总横向力进行了实验研究，同时测量了总的顺向波浪力。分析了横向力的统计特性和频谱特性。将群桩横向力与单桩横向力之比定义为横向群桩系数KCL。本文给出了桩群横向系数CLC和KCL随相对桩距和KC数变化的关系。研究了波浪力、横向力和顺向力的合力与顺向力的比值以及合力系数的变化规律。
The total transverse forces on each of two piles in a side-by-side arrangement and a tandem arrangement were experimentally investigated in irregular waves and the total in-line wave forces measured simultaneously. The statistical and spectral characteristics of the transverse forces were analysed. The ratio of the transverse force on each pile in group to that on a single pile was defined as the transverse grouping-pile factor KCL. Both the transverse coefficients CLC and the KCL for each pile in array was varied with the relative pile distance and KC number and their relationships are presented in the paper. The ratio of the resultant wave force on in-line forces and transverse force to the in-line force and the variation of the resultant coefficient were also investigated.
