摘要
以郑州一开封城市通道箱涵顶进工程为例．分析了大断面箱涵施工中管棚的力学作用机理。论述了管棚的加固和、承力作用，从理论上进行了管棚在箱涵顶进施工过程中的受力分析．结合工程的实际情况验证了管棚的承载作用。
Taking the project of the highway from Zhengzhou to Kaifeng city applying the method of box-culvert advancing as an example, the mechanics action mechanism of the big cross section box-culvert advancing is analyzed. The action of the pipe roof reinforcement and supporting is firstly discussed and then the forces of the pipe roof in the process of the box-culvert advancing are theoretically analyzed. Finally, the bearing capacity of the pipe roof in the box-culvert advancing is proved.
