摘　　要：在大型水利输水工程中,对于跨建筑物、大江大河、深沟峡谷采用渡槽施工技术已很普遍。向家坝灌区工程木桥沟渡槽槽体采用三向预应力矩形槽,通过分析研究,木桥沟渡槽槽体支撑体系采用钢管立柱+贝雷片梁+钢管满堂架支撑系统能够满足槽体施工的受力需求。In large-scale water conservancy and conveyance projects, it is common to use aqueduct construction technology for crossing structures, large rivers and deep gorges. Three-way pre-stressed rectangular trough is used in Muqiaogou Aqueduct body of Xiangjiaba Irrigation Area Project. Through analysis and research, the support system of the tank body in Muqiaogou Aqueduct is composed of steel pipe pillar + Bailey sheet beam + steel pipe full-frame support system, which can meet the stress requirements of the tank body construction.
