摘　　要：大截面大跨度预应力梁支撑体系具有综合性较高,安全风险较大等特点。以武汉市某高职院校理实一体化大楼项目为例,论述大截面大跨度预应力梁支撑体系的设计与施工,通过支架材料选型、确定搭设参数、构造加固措施、结构验算、优化施工工艺、安全保证等措施,解决了大截面大跨度预应力梁高支模技术难题,同时也兼顾了质量、安全与成本。The support system of large-section and large-span prestressed beam is characterized by high comprehensiveness and high safety risk. The design and construction of large-section large-span prestressed beam support system is discussed, with the project of a building in a higher vocational college in Wuhan as a case study. Through selecting support material type, determining erection parameters, reinforcing structures, structural verification, optimizing construction process and ensuring safety, the technical difficulties of high-support moulding of large-section large-span prestressed beam are solved, construction quality, safety and cost are also taken into account.
