等效长度系数修正法在导管架桩自立校核中的应用

Pile Freestanding Analysis with Equivalent Length Method

针对中等水深(70m^130m)群桩式导管架桩体的设计,提出了一种优化的计算方法。此方法从桩体受力分布的角度对长度系数K进行优化。使得稳定性计算结果更接近桩体真实的受力情况,减少不必要的保守带来的投资的增加,并降低导管架结构的设计难度。

In view of the medium water depth （70-130 m） for group pile jackets, with part of pile being above water level, the environment force acting on the pile is very big, and the pile＇s stability is poor. A method is put forward to optimize the calculation. This method considers the stress distribution on pile and adjusts the length factor K to achieve the optimization, so as to make the calculation result more close to practical engineering and reduce the investment.
