| Abstract: | 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. |
