建立预应力混凝土T梁的有限元空间计算模型,考虑徐变作用,计算存梁期T梁上拱度,分析上拱度的主要影响因素,与实际测量结果比较,证明计算方法合理.计算分析表明,混凝土弹性模量和预应力为影响T梁存期上拱度的重要因素,可以通过调整施工参数控制T梁存期上拱度;采用规范方法,计算上拱度结果偏于保守;结果可为相关设计施工提供依据. The finite element space calculation model of prestressed concrete T-beam was established. The calculation method was to calculate the finite element space calculation model of prestressed concrete T-beam, calculate the camber of T-beam during the storage period, and analyze the main causative factors of camber. Compared with the actual measurement results, It shows that the elastic modulus and prestress of concrete are the important factors that affect the camber of the T beam. The camber of the T beam can be controlled by adjusting the construction parameters. For the standard camber method, the camber results are conservative. The results can be related design Construction provides the basis.
