| 摘 要： | 桥梁预应力施工中经常会遇到实际伸长量与设计伸长量不符，且差值较大的情况。采用不同的计算公式计算出的伸长量也有不少的差异,通过部分连续梁张拉数据并针对施工中遇到的问题作了较详细的分析，总结出一套较适用于现场施工的钢绞线实测伸长量的计算方法。

| Abstract: | During prestressing construction of bridge, it often appears the situation that the real elongation is not conformed to the design elongation and often with larger difference. The elongations calculated according to different calculation formulae are also different greatly. Based on the data of part continuous girders' tension and to counter the problems met during construction, a detailed analysis is carried out and a calculation method for real-measured elongation by steel twisted wire which is adaptable for site construction is summarized. |
