摘    要:桥梁后张法预应力梁端锚下混凝土局部承受很大压应力,在工程中张拉钢绞线时会遇到锚下受压区混凝土开裂的情况。通过计算、经验进行适当地配筋以及改进张拉工艺就可以避免这种情况的发生。

关 键 词:混凝土梁 后张法 裂缝 预应力钢绞线 张拉控制应力

Abstract:Concrete under anchor on the end of beam partially bearing very strong compression stress with bridge post stressing prestress.The situation will be appeared that is compressive region concrete under anchor cracking during the steel strand being pulled in project.According to the calculation and experience,proper reinforcing and improving the stretching technique can avoid this situation.
Keywords:concrete beam  post stressing  rift  prestressing steel strand  stretching control stress
