CORRELATION BETWEEN SOIL LIQUEFACTION DURING EARTHQUAKE AND CPT DATA

Modeling Soil Liquefaction Hazards for Performance-Based Earthquake Engineering

Comparing Liquefaction Phenomena Observed during the 2010 Maule, Chile Earthquake and 2011 Great East Japan Earthquake

On February 27, 2010, the central-south part of Chile was affected by a strong ground motion of Magnitude 8.8, that induced moderate values of peak ground acceleration (PGA) on rock outcrops, in the range of 0.13g to 0.32g, while in soil deposits, a maximum PGA of 0.94g was recorded. The duration of the shaking was close to two minutes as it is substantiated by the available acceleration record...

A unified classification model for modeling of seismic liquefaction potential of soil based on CPT

The evaluation of liquefaction potential of soil due to an earthquake is an important step in geosciences. This article examines the capability of Minimax Probability Machine (MPM) for the prediction of seismic liquefaction potential of soil based on the Cone Penetration Test (CPT) data. The dataset has been taken from Chi-Chi earthquake. MPM is developed based on the use of hyperplanes. It has...

Evaluation of Soil Liquefaction Potential by Sensitivity Analysis, Reliability and Data validation

In this study, it is attempted to analyze sensitivity and reliability in order to evaluate the liquefaction potential in soil layers in Tabriz. 62 boreholes that had possible conditions for liquefaction were selected. Seismic mapping was simulated using finite fault method and then the effect of soil layers on PGA was estimated. In continue, the liquefaction potential index was estimated and th...
