针对后张法预应力T梁张拉控制应力在施工中调整的研究,介绍了测试管道摩阻和锚具摩阻的方法,利用测试结果,计算出施工中的锚外控制应力。通过该计算方法得出的控制应力进行施工,施加于梁体的有效应力同设计应力相吻合。 Aiming at the research on the adjustment of tension control stress of post-tensioned T-beam in construction, the method of testing the friction of pipeline and the friction of the anchorage is introduced. The test results are used to calculate the stress of external anchorage in construction. The control stress obtained by the calculation method is used for construction. The effective stress applied to the beam body is consistent with the design stress.
