预应力钢绞线理论伸长值与实际伸长值的偏差分析

Deviation Analysis Between Elongation in Theory and in Practice of the Prestressed Steel Wires

对现行的《公路桥涵施工技术规范》(JTG/T F50—2011)中理论伸长值计算公式及实际伸长值计算公式进行理解和完善,分析了引起理论伸长值与实际伸长值产生偏差的原因,提出了工程实践中应采取的措施。

This study understand and improve the formula of elongation value of theory and measured of existing Norm of Highway and Bridge Construction Technology（JTG/T F50—2011）.Analyses the causes of deviation on the elongation value of theory and measured and proposed measures to be taken in engineering practice.
