摘要
大型长距离有压管道输水工程中,管道穿越公路、埋设于路下或河底等特殊地段,通常采用钢管外包混凝土结构型式。针对高压输水管道钢管外包混凝土结构的力学特性,提出了一种新型无粘结钢管外包混凝土组合结构型式。文中通过南水水库供水工程实例阐述该组合结构的力学模型、工作机理和优势。
In the large-scaled water transport project for a long distance via pressurized pipelines,the composite structure of unbonded steel tube encased by concrete is usually applied in such special senarios as the pipeline crossing the highway,buried under the road or under the river,etc..In terms of the mechanical characteristics of the composite structure of steel tube encased by concrete for the high-pressure water transfer pipeline,a new type of composite structure of unbonded steel tube encased by concrete is proposed.By analyzing the water supply project of Nanshui Reservoir, this thesis focuses on the mechanical model,working mechanism and advantages of composite structure.
