Abstract

A detailed analysis and statistics on the construction status of railway tunnels and construction and planning status of extralong and highspeed railway tunnels in different periods in China are conducted, and the results are clearly and intuitively reflected in figures and tables, providing detailed data for analyzing the development history of China′s railway tunnels. With the development of China′s economy, the scale of railway construction in western China is increasing year by year, and railway tunnels in highaltitude areas and highintensity seismic areas and superdeep buried and extralong railway tunnels are constructed on large scale. It is urgent to deeply study the intelligent construction technology, the construction technology of ultralong deepwater crosssea railway tunnels and the intelligent operation and maintenance technology of the railway tunnels.

Key words： railway tunnel; extralong railway tunnel; high speed railway tunnel
