32米T梁后张法预应力的混凝土在整个铁路的桥梁工程施工的过程中已经得到普遍的应用,在质量的双控指标涉及的钢绞线的施工产生的张拉力相应的计算以及对张拉的伸长值进行的测量,做出的相应规范都已经有了比较明确的规定。但是在对于预应力产生的张拉在实际的施工过程中的相应具体的控制以及测量,存在着很多种说法并且都有非常大的差异,本文将以预应力的混凝土32米T梁作为研究的对象。
The post-tensioned concrete of 32 m T beam has been widely used in the process of bridge construction of the whole railway. Corresponding calculation of tensile force caused by the construction of steel strand involved in the double-control index of quality, Pull the elongation value of the measurements made by the corresponding norms have been more clearly defined. However, there are many explanations and very different differences in the concrete control and measurement of the prestressing tension in the actual construction process. In this paper, a prestressed concrete 32 m T beam will be considered Object
