Study on the Lateral Dynamic Response of Pile Foundation in Liquefiable Soil Layer

Abstract eng:
The reasonability of the main computational method of seismic lateral capacity of pile is discussed and the disadvantages of the pseudo-static and coefficient-discounted method are also pointed based on the shaking table test. The p-y curves are got in the paper indicate both the co-efficient-discounted method and using lateral displacement of pile instead of soil-pile relative displacement are not agreeable with the real situation; Fundamental idea of pseudo-static method is not agreeable with mechanism in actual. The pile response can not be obtained simply by discounting lateral stiffness of non-liquefiable soil layer. Calculated results by using pseudo-static method disagree with real situation especially in small displacement range. Calculating results by using pseudo-static method are quite conservative even can not be accepted in engineering practice.
