| 摘 要： | 文章介绍斜交箱梁板钢绞线长度及弯起转角度的计算方法。箱梁位于腹板的钢绞线是三维曲线，若简化为平面曲线进行计算，将使下料长度和竖向弯起角与实际有不可忽视的误差，并影响张拉伸长量的计算结果。

| Abstract: | The calculation method of length and inclined angle of the steel strands in the inclined pre-stressed box-girder is introduce in this anticle.The steel strands in the web of the box-girder is a three-dimensional curve.If simplify the curve as a plane curve,there will be deviation of the cutting length and vertical inclined angle that can not be ignored in practice and the calculation results of stretching extension value can be influenced. |
