Study of Ground Lateral Flow on Piles Foundation due to Soil Liquefaction

Wei Yu, Xuan Guo

Abstract

The case studies on the damaged pile foundation caused by lateral flow due to soil liquefaction during the big earthquake were discussed. The distributed load method was utilized to calculate the stress and displacement. The effect of the lateral flow to pile foundation in liquefiable soil also is simulated. Through compared the analysis result to the site dig-investigate report, the mechanism of the damaged pile modes were conjectured very well. the calculated stress and deformation of piles indicated good agreement with the actually observed one. The practicability and availability of the distributed load method was substantiated.
