摘要
为提高小半径曲线梁桥的安全性,利用三维空间结构分析程序,对不同曲率半径桥梁结构的结构内力和位移进行了计算和比较,分析了桥跨的内力、位移与弯桥圆心角的关系,并对其设计和计算提出了相应的建议。
For enhancing the safety of the small-radius curved girder bridge, a 3D finite element soft- ware program is used to calculate and compare the internal force and displacement of bridges with dif- ferent radius of curvature. The relationship between central angle and internal force and displacement is analyzed. Finally, the corresponding suggestions for the design and calculation are put forward.
