Study on Numerical Simulation of Pile Group Foundation by Pile Tip Grouting in Beijing-Shanghai High-speed Railway
摘要
Abstract
The previous studies on pile foundation post-grouting technology are mainly limited to single pile.However, group pile is the major structure of pile foundation in engineering at present, which is designed based on deformation control.According to computer simulation static test of group pile foundation in BeijingShanghai high-speed railway post-grouting test section under normal state, the load-settlement law is studied using FLAC3D finite difference software.It is verified the effect of pile tip grouting on reduction of group pile foundation settlement within design load.关键词
