摘要
以国家奥林匹克公园地铁某支线站3根试桩的单桩竖向抗拔静载试验为依据,运用有限元理论对桩支盘附近土体进行了分析,研究了桩周土受力过程应力—应变的变化,从而为挤扩支盘桩设计提供参考。
This paper is to study the working behavior of the soil block and process of soil stress changing principle. It is based on the practical experiment of three uplift force bearing pile which is located in a subway stop nest to the National Olympic Graden. This paper is a reference material for designer of DX pile.
