以控制差异沉降为目标的复合桩基优化设计探讨
Optimum Design of Composite Pile Foundation
目前以变形为控制条件的复合桩基设计理论是桩筏基础研究中的热点问题,而人为合理的调整地基土刚度和桩基支承刚度的方法是控制复合桩基差异沉降的有效手段之一。本文从优化设计的角度出发,考虑上部结构、基础和地基的共同作用,讨论了设置变刚度垫层、改变桩长、桩径、桩距及布桩方式对基础差异沉降和内力的影响,并提出了复合桩基优化设计的发展方向。
For composite pile foundation, differential settlement controlling becomes more and more important now. And adjusting the rigidity of subsoil and the piles is one of the significant ways to make the settlement balanced. Considering the interaction on superstructure- pile foundation-ground, some problems of Optimum design is discussed in this paper, showing how the changing stiffness of piles and the existence of variable stiffness cushion influence the differential settlement.
