通过一实际工程案例,阐述了基于承载力和沉降双控的复合桩基的设计过程,探讨了沉降控制复合桩基在设计过程中需要考虑的诸多问题,进而论证了沉降控制复合桩基在上海地区高层建筑中应用的可行性,达到了较好的经济效益和社会效益。 Through a practical engineering case, the design process of the composite pile foundation based on dual control of bearing capacity and settlement was described. Many problems that need to be considered in the design process of the settlement control composite pile foundation were discussed, and then the settlement control composite pile foundation was demonstrated in Shanghai. The feasibility of application in high-rise buildings in the region has achieved good economic and social benefits.
