摘　　要：温州市中普陀寺佛教文化园喜菩提项目屋面结构采用大跨度非预应力钢筋混凝土梁,其挠度和裂缝控制是重要指标。施工中通过确定合理的起拱高度,对支模架、模板、钢筋、混凝土等施工工序进行严格的过程管理,完成了混凝土浇筑工作,大梁跨中挠度和外观质量均符合设计和规范要求。The roof structure of Wenzhou Zhongputuo Temple Buddhist Culture Park Xi Bodhi project uses long-span non prestressed reinforced concrete beams, deflection and crack control are important indicators. During the construction, by determining a reasonable arch height, strict process management of the construction processes such as supporting frame, formwork, reinforcement and concrete, the concrete placement was completed and the span deflection and appearance quality of the large beam met the design and specification requirements.
