Abstract
This article discusses the design strategy of complex mountain highway bridges. During the research phase, details were obtained based on prior literature review and analysis of engineering materials from mountainous area bridges. After analyzing the design characteristics of complex mountainous area road and bridge projects, the principles for the design of bridges on complex mountainous area expressways were proposed. The research on bridge design was carried out from five dimensions: bridge type selection, foundation design, superstructure design, connection part design, and material and technological innovation. Eventually, a relatively complete design system was formed. It is expected that this paper can provide technical references and value for road and bridge projects in China and promote the sustainable development of China's road traffic system from a macro perspective.
