摘要
连续箱梁平曲线半径较小时 ,如果只考虑预应力管道竖曲线的转角计算管道摩阻 ,其作用于箱梁的有效预应力的计算就会出现较大误差。从理论上对连续弯梁桥空间转角进行了分析和计算 。
As the radius of horizontal curve of the continuous box girder is too small, if only the bending angle of prestressed duct vertical curve is considered in the calculation of friction stress, the calculation of box girder's effective prestress will be too much erroneous In this paper, the space bending angle of continuous curved bridge is analyzed and calculated theoretically, and the practically approximate calculation method is given
