Abstract

The development process of railway tunnel construction in China is briefly introduced, especially the great progress made in the 40 years of reform and opening up. Among the 16 798 railway tunnels with a total length of 19 630 km completed and operated, 12 412 have been completed in recent 40 years, with a total length of 17 621 km, accounting for nearly 90% of the total length of railway tunnels in China. A series of achievements of railway tunnels in China are summarized from the aspects of tunnel design theory and method, construction technology and equipment, construction materials, disaster prevention and rescue, facility detection and maintenance, and the development status and technical characteristics of railway tunnels in different periods are expounded through representative tunnel projects. Combined with the technical problems and challenges currently faced in the railway tunnel engineering, the development directions of active support and cooperative control concept and technology, digitized survey and design, intelligent construction, and intelligent operation and maintenance are put forward.

Key words： railway tunnel; design method; standard system; structure system; risk management; disaster prevention and rescue; construction technology; mountain tunnel; underwater tunnel; loess tunnel; karst tannel; urban tunnel; active support; intelligent construction; intelligent operation and maintenance
