预应力张拉伸长量的计算与量测

Calculation and measurement of prestressed stretching extension value

针对伸长值的计算与量测在桥梁施工中的重要环节,分别介绍了理论伸长值和实际伸长量的量测与计算,并分别提出了计算伸长量时应注意的问题,以供有关技术人员在施工时参考。

Aiming at the important segment of stretching extension value calculation and measurement in the bridge construction, the theoretical extension value and practical extension Value calculation and measurement were introduced individually and the problems need attention in the calculation process were proposed, which can be referenced for the engineers.
