摘　　要：砂土在地震荷载作用下极易发生液化,液化土地基对建筑物造成的危害不可忽视。分析了液化的机理、影响因素及现行的研究、处理方法。通过实例说明:CFG桩和碎石桩共用,对处理内蒙古地区砂土液化,具有明显的抗液化效果。最后,提出CFG桩和碎石桩抗液化需进一步研究的问题。As sand soils under the action of earthquake loading are liquefied easily, hazard of sand soil liquefaction to the foundation of buildings can＇ t be neglected. In the paper the mechanism, influence factors and present treatment of the liquefaction are analysed. The engimeeing cases demonstrate that CFG pile and crushed stone pile can achieve good effect to prevent the liquefaction in Inner Mongolia. At last, in the paper some questions being studied further are put forward.
