Evaluation for Earthquake Liquefaction of Loess Sites

ugh the sinusoid loading dynamic triaxial test, the liquefaction property of saturated loess and sand selected from a civil airport of Lanzhou, Gansu is examined. Based on the laboratory results, a comprehensive assessment on the earthquake liquefaction potential of the loess and sand is given, using the liquefaction resistance shear stress method and the results of seismic hazard assessment. It is found that under the effect of ground motion with exceedance probability of 10% within 50 years, the loess in the study is more susceptible to liquefaction than sand.
