Article Title: Study on Dynamic Behavior for Pile-Soil-Bridge Structure Seismic Interaction in Liquefying Ground under Strong Earthquake
by Baydaa Hussain Maula, Ling XianZhang, Tang Liang

Abstract:
Pile foundations for bridge usually built in different types of liquefiable soils and might suffer from the severe damage in destructive earthquakes. Therefore, it's necessary to investigate the problems related to seismic response of single-pile foundation in liquefiable soils with different soil layers. For these purposes, shaking table test that involved seismic soil-pile-bridge structure interaction (SSPSI) in liquefiable three-layer ground had been conducted, subjected to a series of El Centro earthquake events with varying shaking level and duration. Three-layer ground consisted of a middle horizontal saturated the sand layer with a surface non-liquefaction clay layer, underlain by a non-liquefaction clay layer. The tests were conducted using the laminar shear box with depth of 2 m and plan dimensions of 2 m and the single-pile foundation which was prefabricated by galvanized iron wire and micro-concrete was used. Superstructures were simulated as the mass. In the note, the macroscopic phenomena displaying the critical information of seismic design of bridge foundations were introduced firstly, and then the important features on time histories of seismic pile-soil interaction systems in different soil profiles were obtained, finally the peak bending moment of the pile were presented for soil profiles.
Keywords: pile - soil - bridge seismic interaction; pile bridge damage response; liquefied sites; strong earthquake, shaking table test
