摘要

饱和砂土在地震荷载作用下极易发生液化,对工程建筑造成危害。本文探讨了地震力作用下饱和砂土的液化机理。通过实例说明CFG桩和碎石桩共用具有明显的抗液化效果,并提出CFG桩和碎石桩抗液化,需进一步研究的问题。
The saturated sand can be easily liquefied by earthquake, which will lead to severe damage to constructions. The article discusses the liquefaction mechanism of saturated sand caused by earthquake,which will provide reliable theoretical basis for the control of sand liquefaction. The engineering cases demonstrate that CFG pile and crushed stone pile can achieve good effect to prevent the liquefaction.Finally, in the paper, some questions about CFG pile and crushed stone pile being studied further are put forward.
