摘要
本文提出一种外海高桩墩式承台的基桩受力最优化数学模型．这种模型考虑了多种荷载工况，从基桩内力分布入手，用序列二次规划法求解最少桩数下的桩基受力最优布置．结合多个工程实例进行计算结果表明，与传统方法相比，可以减少１０～２０％的基桩数目，且基桩受力大为改善．
The optimization mathematical model of the pile forces for offshore piled breasting dolphin is presented in this paper.The forces acting on the pile under various conditions are analyzed.The optimum layout of the least number of piles is calculated by the method of sequential quadratic programming (SQP).Several project examples have been calculated by using this model and compared with the traditional design method.It is shown that the number of piles can be reduced at least by 10 20% and the qorces acting on the pile ane im poroved obriously.
