群桩基础优化设计及其在工业厂房中的应用

在讨论桩基承台破坏机理的基础上，给出群桩基础设计的优化方法。桩在承台上采用最优化方式布置，承台优化设计的目标函数为承台混凝土的体积，约束函数考虑承台抗剪切、柱冲切、角桩冲切和沉降等，优化设计由编制的程度完成。通过一工业厂房基础设计的实际应用表明本文优化方法高效实用，并可产生较大的经济效益。

Optimum Design for Pile Group Foundation and ItsApplication in Factory Building

On the basis of discussing the damage mechanism of cushion cap, a method of optimum design for pile group foundation is put forward in this paper.The piles are decorated on the cushion cap which makes the area of cushion cap minimum.The object function of optimum design for cushion cap is its volume and the binding functions are the requirements of shear, column die cutting, corner-pile die cutting and settlement for cushion cap.The optimum design has been done by a computer program. This method is used to design a factory building. The final result suggests that this method is highly effective and practical. A fair-scale economic efficiency can be obtained in ifs practical use.
