摘要
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 forces of random wave groups with different groupiness factor and runs on a vertical cylinder whose diameter could be selected were tested in a wave tank. It is found from the experiment that the ratio of wave peak forces does not vary with the run of wave groups, whereas it grows with the increase of the wave groupiness factor and the force run is less than the wave run because the cylinder is a nonlinear system. The ratio of wave peak force grows not only with the increase of the KC number but also with the decrease of the shape factor m of the Weibull distribution, i. e. , with the increase of the wave groupiness factor GF.
