大断面箱涵施工中管棚的承载作用机理分析

The analysis on load mechanism of steel pipe shed in large section box culvert construction

分析了大断面箱涵施工中管棚的作用机理,并结合工程实际验证了管棚的承载作用,为箱涵顶推施工中管棚支护提供了理论依据。

The load mechanism of steel pipe shed in large section box culvert construction is analyzed in this paper. The load ability of steel pipe shed is tested through a real engineering too and this will provide a theoretical gist for the shed support and protection in box culvert propulsion coustruction.
