摘　　要：随着国内各大城市地下空间的不断开发和利用,地下结构越来越多,地震中饱和砂土、粉土地层的液化是造成地铁结构破坏的重要原因之一。通过分析某城市地铁区间的粉土液化,对可液化粉土提出了处理方案,并达到了预期的处理效果,以便类似项目参考借鉴。With the continuous development and utilization of underground space in major cities in China,there are more and more underground structures.Through the analysis of the liquefaction of silt in the subway section of a city,the paper puts forward the treatment scheme for the liquefiable silt,and achieves the expected treatment effect,so as to provide reference for similar projects.
