摘要
近海软基条件中跨海桥梁和风电场工程大多采用承台桩基结构。圆形承台波浪力的计算采用基于线性势流理论和特征函数展开的解析方法,桩柱波浪力的计算采用Morison公式,讨论并发展了波浪对圆形承台及其下部桩柱的作用力的工程计算方法。研究了承台的存在对桩基波浪力的影响,针对某典型桩基结构布置形式给出了承台效应系数和群桩系数随相对水深、无量纲承台半径、相对浸深等参数的变化规律。
An engineering approach for computation of wave loads acting on pile-slab structures in regular waves was studied. The wave loads on the slab were computed by the linear potential theory and an eigenfunction expansion method. The wave loads on piles were evaluated by using Morison formula. The influence of the slab for the wave loads on the piles was discussed in terms of the influence coefficient of slab and the coefficient of grouping pile effect. For some typical structure form, the variation of these two coefficients with the involved parameters were shown.
