Analysis and Research on Sand Vibrating Liquefaction

The saturated loose sand soil loses its strength and then turns into fluid state rapidly under the live loading.Vibrating liquefaction is a special strength problem,and with strength of significant losing suddenly as characteristic.So intensive study of the basic rule with the deformation greatly and the mechanism of the generation of the saturated sand soil after liquefaction,that forecasts and prevents danger resulting from seismic liquefaction.This text mainly aims at the seismic liquefaction problem of the saturated sand soil,from liquefaction of mechanism,liquefaction possibility judgment etc.to obtain more systemic analysis and summary,and takes the study of the liquefaction of saturated sand soil with relative papers and investigations.Consequence kinds of estimation methods of liquefaction possibility have been summed up,such as analysis of liquefaction stability and deformation etc.There will be certain effect on research about forecasting of saturated sand soil liquefaction and preventing danger resulting from seismic liquefaction.
