Application of Digital Technology in Road and Bridge Design

With the development and progress of science and technology, road and bridge design has experienced rapid development, from the initial manual drawing design to the popularity of Computer-Aided Design (CAD), and then to today’s digital software design era. Early designers relied on hand-drawn paper design forms which was time-consuming and error-prone. Digital support for road and bridge design not only saves the design time but the design quality has also achieved a qualitative leap. This paper engages in the application of digital technology in road and bridge design, to provide technical reference for China’s road and bridge engineering design units, to promote the popularity of Civil3D and other advanced design software in the field of engineering design and development, ultimately contributing to the sustainable development of China’s road and bridge engineering.
