摘　　要：结合涔天河水库扩建工程西干渠标段渡槽施工,以单跨最高高度58m的弄石渡槽为研究对象,分析工程施工的主要难点,提出采用高大组合支撑体系施工技术,对渡槽支撑体系主要结构设计进行详细阐述。实践证明,高大组合支撑体系施工技术能够减少支撑体系基础混凝土和钢管的用量,节约工程建设投资,降低施工安全风险,大大加快工程施工进度。Combined with the aqueduct construction of the West Trunk Canal section of the expansion project of Centianhe Reservoir,this paper takes the single-span Nongshi aqueduct with the highest height of 58 m as the research object,analyzes the main difficulties of the construction,puts forward the construction technology of tall composite support system,and expounds the main structural design of the aqueduct support system in detail.Practice has proved that the construction technology of the tall composite support system can reduce the amount of concrete and steel pipe in the foundation ofthe support system,save project construction investment,reduce construction safety risks,and greatly accelerate theconstruction progress.
