摘要
简述了预制梁布置预应力筋的作用，根据结构力学挠曲变形原理，分析了有关梁体挠度的计算方法，根据挠度计算结果，即可解决预拱度的设置问题。
The function of settling pre-stressed bar in precast beam is introduced. According to bending deformation theory in structural mechanics, the author analyzes the calculation method of beam＇s deflection, and solves the setdement of career by the deflection result.
