摘要
基于Morison方程和线性波及线性波浪谱理论,经过系统的大量的实验研究,探讨了单柱与串、并列双柱在规则波和不规则波与水流共同作用下,圆柱上所受正向力、升力及其合力的特征。从而给出了单柱上速度力系数C_d、惯性力系数C_m及升力系数C_l与KC数的相关关系以及串、并列双柱所受正向力、升力及合力的群桩影响系数与相对桩距和KC数之间的相关关系。
A serious model test of wave forces by both regular and irregular waves combined with currents on single pile and bipile in tandem and parallel array has been carried out. Based on Morison Equation, linear wave theory and linear wave spectrum theory as well, the characteristics of inline, lift and resultant forces on cylinders were analyzed respectively. The drag, inertia and lift coefficients CD, Cm and CL for single pile as well related to KC number and the grouping effect coefficients of inline, lift and resultant froces on bipiles in tandem and parallel array related to KC number were given in this paper.
