Abstract: Sands that did and did not liquefy at two sites during the 1979 Imperial Valley, Calif., earthquake

Abstract: A technique is developed for compiling liquefaction hazard maps by mapping a parameter termed liquefaction severity index (LSI). LSI, a measure of ground failure displacement, is based on the displacement of lateral spreads ...

Abstract: To provide design guidance on the influence of soil softening on ground response, we analyzed ground motions recorded at five instrumented liquefaction sites, including the Wildlife Liquefaction Array, Calif.; the Port ...

Abstract: Although liquefaction is a major cause of earthquake damage, little harm occurs unless the liquefied condition leads to some form of ground disruption or ground failure. Thus, the ability to accurately predict potential ...

Abstract: In response to an urgent need for field data from instrumented liquefaction sites, the U.S. Geological Survey in 1982 selected and instrumented a site in southern California called the Wildlife site. Two accelerometers ...

Abstract: This paper presents an empirical model for predicting the amount of horizontal ground displacement resulting from liquefaction-induced lateral spread. The model was developed from multiple linear regression analyses of ...

Abstract: Automatic trip hammers have advantages for standard penetration test (SPT) of consistent drop height and low friction loss during hammer fall. These advantages, however, generate high energy transfer ratios (ER), typically ...

Abstract: In 1992 and 1995, Bartlett and Youd introduced empirical equations for the prediction of lateral spread displacement; these equations have gained wide use in engineering practice. The equations were developed from the ...
