摘要
通过由CFG桩与二灰桩组合而成的长短桩复合地基处理某30层高层建筑软弱液化地基的工程实例,探讨了这一类型复合地基的承载力与沉降变形的设计计算方法,并与建筑物实测的承载力、沉降值进行了对比研究。从中可看出:这种处理方法使原地基土消除了液化,满足了上部结构对地基承载力、变形的要求,同时也验证了所提出的设计计算方法的可行性。
A case of the long-short-pile composite foundation in liquefied soil under a 30-stoeryed high-rise building is presented, in which the long and short piles are made of CFG and lime. A new design method of the foundation treatment is introduced, and the calculated value is compared with the actual measurement. The results show that the liquefaction of soft ground is eliminated and the demand of load and settlement for upper building is met. At the same time, it is proved that the design method is available.
