在波浪槽中进行了具有不同群因子和连长的随机波群对三种直径的桩柱作用力的实验研究,指出波浪峰力的比值不随波群的连长变化,而随波群因子的增加而增大。由于桩柱是一非线性系统,作用力的群团子大于波浪的群因子,其连长小于波浪的连长。波浪峰力的比值不仅随KC数的增加而增大,还随波群因子GF的增加而增大。 The experimental study on the forces acting on the piles of three diameters by random wave groups with different group factors and their length was carried out in the wave tank. It is pointed out that the ratio of wave peak force does not change with the continuous length of the wave group, Increase and increase. Because the piles are a non-linear system, the grouping of forces is larger than the group factor of the wave, and its associated length is smaller than the length of the wave. The ratio of wave peak force not only increases with the increase of KC number, but also increases with the increase of wave group factor GF.
