箱涵顶进施工中管棚力学作用机理研究

Study on the Mechanical Mechanism of Pipe Roof in the Jacking of Box Culvert

分析大断面箱涵施工中管棚的加固作用和承载机理,并结合郑开城市通道顶推箱涵项目工程实际验证管棚的承载作用,为箱涵顶进施工中管棚支护提供理论依据。

The reinforcement function and load mechanism of pipe roof in large section box culvert construc- tion is analyzed, and combined with the jacking of box culvert construction for Zhengzhou - Kaifeng Route way, the load function of pipe roof is verified, and meanwhile, provided theoretical foundation for using pipe roof in the jacking of Box Culvert.
