摘　　要：在水利工程中,采用渡槽跨越江河、山沟、建筑物已很普遍,渡槽跨度大、槽身高、施工难度大。以四川省向家坝灌区一期一步工程木桥沟渡槽槽身为研究对象,介绍了木桥沟渡槽施工流程与预应力施工技术,结合充水试验监测数据对槽身施工效果进行评价。结果表明严格按照技术要求施工渡槽质量能够满足设计要求。In hydraulic engineering,it is common to use aqueducts to cross rivers,mountain gullies,and buildings.Aqueducts have the characteristics of large span,high height,and difficult construction.Taking One Phase One Step Project of Xiangjiaba Irrigation District in Sichuan Province as the research object,this paper introduces the construction process and prestressing construction technology of the Muqiaogou Aqueduct,and evaluates the construction effect of the culvert body based on the monitoring data of the water filling test.The results indicate that strictly following the technical requirements for the construction of aqueduct can meet the design requirements for quality.
