Abstract

Abstract

This paper presents test results of sand liquefaction under sinusoid loading at a site of one Changde-Zhangjiajie expressway bridge using the DSD-160 electric-magnetic vibration triaxial apparatus.A new method for evaluating sand liquefaction based on dynamic triaxial apparatus is proposed in combination with an earthquake shear stress time history method.The results show some clear evidences for the potential sand liquefaction under earthquake ground motion with different exceedance probability.A risk classification is also given.These results not only prove the feasibility of the new approach on evaluation of sand liquefaction,but also help to gain a better understanding of the seismic resistance design before the construction of the bridge.
