摘要： Liquefaction often causes damage to infrastructure such as buildings, bridges, and lifelines. Liquefaction-induced ground movements such as settlement and lateral spread are of major concern to engineers who have to evaluate seismic risk. This paper deals with evaluation of liquefaction-induced settlement using a cone penetration test (CPT). Existing CPT-based models often overestimate liquefaction-induced settlement. In this paper, a database of case histories of settlement in recent earthquakes is compiled and used to calibrate the model bias of a CPT-based model, from which a simplified procedure is developed that allows for estimation of the probability of exceeding a specified settlement at a given site. Reasonable results are obtained using the developed simplified CPT-based model, as demonstrated in the examples presented. 出版者： Ottawa, ON: NRC Research Press 出版日期： 2013-10-01 出處： Canadian geotechnical journal, 2013-10, Vol.50 (10), p.1055-1066 版權： 2015 INIST-CNRS 版權： COPYRIGHT 2013 NRC Research Press 版權： Copyright Canadian Science Publishing NRC Research Press Oct 2013 識別號： ISSN: 0008-3674 識別號： EISSN: 1208-6010 識別號： DOI: 10.1139/cgj-2012-0410 識別號： CODEN: CGJOAH
