SEISMIC RESISTANCE OF PILE FOUNDATION IN LIQUEFACTION LAYER

Guo Jin-tong

Abstract

The behavior of the model pile in the liquefying saturated sand layer during shake is studied through the shake table test,and some results about the soil-pile dynamic interaction are obtained. According to the test results,the dynamic and static behavior of reaction force and displacement of the saturated sand in different depth is analyzed and compared. The lateral resistance of the soil decreases after the sand has liquefied,but it does not lose completely. So it is conservative that the lateral resistance of the liquefied soil is not considered when the pile in the liquefied soil is designed.
