Abstract

Abstract

The influence of different compatibility conditions between pile and soil on the dynamic response of a single pile embedded in a saturated soil and subjected to P,SV waves is investigated.According to the fictitious pile methodology,the pile soil interaction system is decomposed into a fictitious pile and an extended half space saturated soil.Based on the fundamental solutions for a circular harmonic patch load,the second kind of Fredholm integral equations for the pile are established via two kinds of compatibility conditions: vertical strain or vertical displacement as well as rotary angle or horizontal displacement.Solution of the integral equations yields the dynamic response of the pile soil system.Numerical results indicate that,except the axial force,numerical results for other variables due to the two compatibility conditions are very close.The research finding is an important criterion for choosing different compatibility conditions for simulating dynamic pile soil interaction.
