Research on Key Problems of Small-and Medium-Span Bridge Design in Low-Grade Highways in Mountainous Areas
With the continuous development of highway bridge construction in China,the scale of the project continuously expands,which puts forward higher requirements for the selection and design of small-and medium-span bridges.This paper firstly discusses the selection and design of bridges from the perspectives of topographic and geological conditions,height-span relationship and structural form;then discusses the selection and design of the superstructure and the selection and design of the substructure,so as to provide reference for more engineering projects.
