| 摘 要： | 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。文章以复合桩基非线性设计理论为基础，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。

| Abstract: | For composite pile foundation, the differential settlement control becomes more and more important now. And adjusting the rigidity of subsoil and the piles is one of the effective ways to make the settlement balanced. Considering the interaction of superstructure-pile foundation-ground, some problems of optimum design are discussed in this paper, showing how the stiffness change of piles and the existence of cushion with variable stiffness influence the differential settlement. |
