Liquefaction Estimation and Hazard Evaluation Criteria of Sand Soil Foundation of Horizontal Ground

Sand liquefaction is a common seismic hazard of foundation. In order to investigate the hazard evaluation criteria of liquefaction of sand soil foundation, a research was made to study different methods of discriminating sand liquefaction with the reference of the results of recent related studies in this area. Through comparisons, the study finds out that the standard penetration test (SPT) is a relative reliable method to determine liquefaction. Moreover, based on the related researches about the estimation and hazard evaluation of sand liquefaction, the procedures and standards of the liquefaction hazard evaluation of sand soil foundation of horizontal ground have been put forward at the end through this study.
