Abstract: In order to evaluate the implementation of the National Medium and Longterm Science and Technology Development Plan (2006~2020), the major technological advancements and innovations of China′s traffic tunnels in the past 14 years are systematically summarized from the aspects of engineering survey, structural design, construction technology and equipment, ventilation and lighting, operational maintenance and environmental protection, etc. And then the future development of tunnel industry is predicted. Finally, new demands and challenges in the areas, i.e. construction technology of ultralong tunnels in complex conditions, construction technology of crosssea tunnel, construction and operation technology of urban underground road network, tunnel complementary comprehensive utilization technology of green renewable energy, intelligent tunnel diagnosis recognition and rapid repairing, intelligent disaster prevention of ultralong tunnels and underground works in complex conditions, are proposed.

Key words: tunnel engineering survey, structural design, construction technology, construction equipment, ventilation and lighting, operation and maintenance, underground road network, intelligent disaster prevention
