Over the past 40 years of reform and opening up, China’s railway tunnel construction industry has made great progress. The completed railway tunnels account for nearly 90% of the total length of China’s railway tunnels. At present, China’s tunnel construction technology is relatively advanced, but with the development of tunnel engineering in the southwest, railway tunnel construction is facing a series of major and complex geological problems. This chapter mainly introduces the tunnel design theory and method, support structure system, construction technology, and equipment under complex geological conditions. In addition to the technical problems and challenges faced by the current railway tunnel engineering, this chapter puts forward the development of active support collaborative control concept and technology, digital survey and design, intelligent construction, and intelligent operation and maintenance, so as to provide a useful reference for promoting the development of tunnel engineering.
