Abstract

Abstract

This thesis is focus on the soil compaction effect due to pile installation. There are PHC pile、CFG pile and MMP pile in one of the Shanghai-Nanjing high-speed railway yard. With theoretical simplified method and the Ansys finite analysis program to estimate the distribution and impact ranges on stress and displacement fields of single pile、vertical piles and pile groups. It is concluded that the influences of squeezing effect of PHC pile on surrounding pile is existence. And some reasonable suggestions on construction sequence are given. The studies of this thesis may have some practical effect in engineering practice.
