摘要
连续梁施工中对竖向预应力精轧螺纹钢筋的控制是一个相对薄弱的环节，而竖向预应力在连续梁中对控制腹板裂纹起重要作用。根据在施工中对连续梁竖向预应力系统进行摩阻试验的经验，总结方便有效的试验方法，供同类工程参考。
During the construction of continuous beam,the control to vertical prestressed rebar is a relatively weak link, while the vertical prestress is playing an important role for the controlling of web cracks in continuous beam.Based on the experience of conducting friction resistance test on continuous beam vertical prestressed system during construction,this ar-ticle has summarized convenient and efficient testing methods as a good reference for similar projects.
