摘　　要：针对深水裙桩式导管架长桩安装时的自由站立工况进行分析,提出一种优化的校核方法。该方法从波浪动力响应影响方面对深水长桩设计进行优化,使得桩自由站立稳定性计算结果更加接近真实的受力情况。与传统方法相比,优化后的设计方法不仅可以减轻桩体和导管架的质量,减少投资成本,而且降低了深水导管架长桩结构设计的难度。For the analysis of the long pile of group pile jackets in deep water in installation condition,a method is put forward to optimize the calculation.This method is optimized from the effect of wave dynamic response,so as to make the calculation result more close to practical engineering,reduce the investment and the difficulty of deep water jacket design of long pile in deep water.
