Experimental investigation on stability of pile foundation baffle permeable breakwater
摘要
Abstract
A phase difference exists between the extreme values of the total horizontal wave force and the wave uplift force.From the perspective of structural stability,the phase difference influences the stability of the pile foundation baffle permeable breakwater.In view of this situation,physical model tests under irregular waves without overtopping were conducted.The results show that a phase difference exists between the extremes of the total horizontal wave force and the wave uplift force,and the two forces do not reach the extreme values at the same time.Compared to the extreme value,the wave uplift force at the time of the peak total horizontal wave force is reduced,and the total horizontal wave force is reduced at the time of the peak wave uplift force.The main influencing factors,including wave steepness,relative breakwater width,relative superelevation,and the relative water entry depths of the front and rear baffles,were comprehensively considered.Using multiple regression analysis,the reduction factors for the wave uplift force at the peak total horizontal wave force and for the total horizontal wave force at the peak wave uplift force were analyzed,and the calculation formula of reduction coefficient was provided.关键词
