摘　　要：本文通过对振冲碎石桩消除饱和砂土液化的机理分析,结合工程实例,应用标准贯入原位测试方法的检测数据和勘察、设计、施工资料,主要从建筑场地水文地质条件的变化方面探讨了某风电场振冲碎石桩消除砂土液化失效的原因,并提出在地下水位较高或地下水具承压性的细砂地区建议慎用振冲法的建议。In this paper, based on the analysis of mechanism of saturated sand liquefaction elimination caused by vibro-replaeement stone colume, and with the data test by standard penetration in-situ measurement and survey, design, construction data of a project example, the author discussed that the reasons why sand liquefaction elimination caused by vibro-replaeement stone eolume is inad- fectual of a wind farmer is the change of the hydrologic geology, and gave a suggestion that the application of vibro-replacement in siltstone area where the groundwater level is high or is confined groundwater should be cared.
