摘要
文中通过考虑水流超高产生的扭矩,并将扭矩简化为分布在弯道内的均布扭矩,利用纯扭转理论,得出弯道型渡槽结构静力的计算方法。以实际直型渡槽作为曲型渡槽的展直模型分析结构受力并相互比较,得出在弯道型渡槽中有剪应力存在,超高引起的扭矩随着流速和曲率的增大而增大,在结构配筋计算中应予以考虑。
Considering the torque caused by water surface super elevation is simplified the uniform torque to distribute in bend aqueduct, the paper concludes the calculation method of bend aqueduct structure static by using the pure torsion theory. Using the actual straight aqueduct as extended straight model of curved type aqueduct,the paper analyzes and compares bearing carrier of the structure, concludes that the shear stress existing in bend aqueduct and the torque caused by water surface super elevation increases with the increasing of flow velocity and curvature, which should be considered in calculation of structure reinforcement.
