In order to improve the stability of the bridge pile foundation,the large diameter pile foundation reinforcement construction technology of the large diameter pile foundation of the highway bridge is proposed.First,the pile foundation of the large diameter bridge is reinforced,then the formwork installation and concrete pouring are placed,and the cracks of the pile foundation are finally closed to complete the construction technical design of the large diameter pile foundation of the highway bridge.The actual construction results show that,compared with the unused pile foundation reinforcement method,the total calculated settlement is reduced after applying the proposed method,which proves that the reinforcement effect of this study is significant.
