摘要:	摘要： The simplified methods based on the cone penetration test (CPT), standard penetration test (SPT), and shear wave velocity ( V s ) test are prevalent in liquefaction potential evaluation. In this study, new case histories with the shear wave velocity measurements and the liquefaction phenomenon observations are compiled from the 22 February 2011 Canterbury earthquakes in New Zealand. The new case histories are combined with the existing V s database for assessing and updating probabilistic models. The widely used logistic regression models, as well as other probabilistic models, are examined in the framework of generalized linear models (GLMs). To this end, the maximum likelihood estimation (MLE) principle is used to determine the model parameters. Then, the developed generalized linear models are ranked using three model assessment criteria. Based on the assessment criteria adopted, the log–log and logistic models are recommended for both the existing and the combined database. The updated log–log model and logistic model are recommended for shear wave velocity based liquefaction potential evaluation. 其他題名： Bull Eng Geol Environ 出版者： Berlin/Heidelberg: Springer Berlin Heidelberg 出版日期： 2016-08 出處： Bulletin of engineering geology and the environment, 2016-08, Vol.75 (3), p.1199-1214 資源來源： SpringerLink Journals 版權： Springer-Verlag Berlin Heidelberg 2016 識別號： ISSN: 1435-9529 識別號： EISSN: 1435-9537 識別號： DOI: 10.1007/s10064-016-0880-8 識別號： CODEN: BIEGB6
