摘要
预应力混凝土施工分为先张法和后张法.一般均实行双控,以张拉控制应力为主,伸长值进行校核.本文通过对后张法施工中参数k和μ的取值对理论伸长量的影响分析,提出伸长量校核的思路;对预应力筋回缩值在伸长量校核时的处理提出了自己的看法.
Prestressed concrete construction are classified as pretensioning as post-tensioning. This text put forward the way of thinking of the elongation indicator amount of proofread from analysis that the value of parametric K and μ with detriment to the post-tensioning construction;The author present own viewpoint with dealing with the prestressed reinforcing steel bar anchorage retracting number at proofread elongation indicator.
