摘要
结合JTJ 041-2000公路桥涵施工技术规范相关规定,针对预应力筋张拉应力校核方法进行了探讨,以具体工程为例,介绍了钢绞线张拉理论伸长值的计算方法及现场量测计算方法,以期指导实践,确保预应力施加准确。
Combining with JTJ 041-2000 Construction Technology Specification Related Regulations of Highway Bridge,according to checking methods of prestressed tendon tensile stress made discussion,take specific engineering as example,this paper introduced the calculation method and field measurement calculation method of steel strand tension theory elongation value,in order to guide practice,ensured prestressed imposed accurate.
