OVERVIEW OF THE FRAMEWORK USED FOR SEMI-EMPIRICAL LIQUEFACTION PROCEDURES A brief overview is provided for the framework that is used as the basis for most semi-empirical procedures for evaluating liquefaction potential of cohesionless soils during earthquakes.

The liquefaction potential index (LPI) was used to prepare quantitative maps of liquefaction hazard in the greater Oakland, California, area. ... LPI, which was developed in Japan to assess liquefaction severity at a specific location, combines depth, cumulative thickness of liquefiable intervals, and factor of safety...

A reassessment of liquefaction potential and an estimate of earthquake induced, free field settements have been conducted for four sites at the DOE Paducah Gaseous Diffusion Plant located southwest of Paducah, KY. ... The reassessment indicates that liquefaction of the granular soils is not likely at the four sites studied.

At the Wadamisaki district sites, we used a large suite of SPT logs cataloged and available in the KOBE JIBANKUN Geographic Information System (GIS) [15] to independently evaluate stratigraphy, liquefaction potential, and target the depth-range of the representative shear-wave velocity of the liquefaction layer.

Cyclic stress ratio versus normalized shear wave velocity for the Wadamisaki district sites. The data fall in a high CSR area populated with no prior data. Solid points are the mean velocities of the liquefied layer. ... Open circles are non-liquefied sites. Ellipses define 1 standard deviation values. ... Back to Report...
