摘　　要：装配式混凝土预制梁具有标准化设计、工厂化生产、机械化施工的优点,在我国公路交通建设中占有重要地位,但预制梁在小半径曲线段的适应性尚无定论,限制了其进一步发展应用。以装配式混凝土预制梁为研究对象,从常规布梁方式入手,分析了影响布梁的主要因素,并归纳推导出适用相应条件的圆曲线最小半径求解公式,其结论及研究方法,可供相似项目参考和借鉴。With advantages such as standardized design,factory production,and mechanized construction,assembled precast concrete beams have been crucial in China's highway transportation construction.However,the uncertain adaptability of precast beams in small-radius curve sections limits their further development and application.Based on the assembled precast concrete beam,starting from the conventional beam deployment method,the main factors affecting the deployment of beams were analyzed,and a formula for solving the minimum radius of the circular curve suitable for the corresponding conditions was deduced.The conclusions and the research methodology could provide a reference for similar projects.
