| Abstract: | According to the pile foundation settlement,and the decrease of bearing capacity and other problems caused by the tunnel excavation of the urban subway,the authors propose a new method of foundation reinforcement,which is called composite bolt pile.Relying on the reinforcement of Fengbei bridge foundation of Beijing subway line 14,the authors introduce the construction process,technical requirements of composite bolt pile,and the potential problems and corresponding solutions during construction.The study is applied in the reinforcement of Fengbei bridge foundation to ensure engineering quality. |
