山区高速公路常规跨径桥梁上部结构设计问题探讨

Discussion on the Conventional Span Bridge Superstructure Design of Mountainous Expressway

随着我国经济建设的发展,山区高速公路建设日益增多,山区高速公路常规跨径桥梁的修建也越来越多。详细阐述了不同跨径、不同墩高对山区高速公路常规跨径桥梁的影响,并给出了设计实例,为解决山区高速公路常规跨径桥梁上部结构设计问题提供了技术参考。

With the development of China’s economic construction,mountainous expressway construction isincreasing,there are more and more conventional long - span bridges of mountainous areas are built. The influenceof different span and pier height on the conventional span bridge of mountain expressway is elaborated,and a designexample is given in this paper,which can provide a technical reference for solving the superstructure design problemof the conventional span bridge in mountain expressway.
