大型互通立交既有桩柱利用方案研究

Research on Existing Piles and Piers Utilization Schemes of A Large-Scale Interchange

文中对某大型互通立交已施工桩柱利用方案进行了介绍,并对各方案采用有限元软件进行动力分析,并验证了各方案的受力合理性。同时,对各方案从施工难度、耐久性、经济性等多方面进行比选,最终推荐了一个合理的既有桩柱利用方案,为同类项目提供借鉴。

In this paper, the utilization scheme of piles and piers used in a large-scale interchange has been introduced, and the dynamic analysis of each program has been carried out using finite element software to verify the rational distribution of force of each scheme. At the same time, various programs were selected from the aspects of construction difficulty, durability, economical efficiency, etc. Finally, a reasonable existing pile and pier utilization program was recommended to provide reference for similar projects.
