STUDY ON THE LATERAL DYNAMIC RESPONSE OF PILE FOUNDATION IN LIQUEFIABLE SOIL LAYER

摘要：

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.
