Abstract: To promote the popularization and application of engineering technology and innovation achievements in the construction of highway tunnels in Yunnan province, China, the achievements in the construction of highway tunnels in Yunnan in the past 30 years are summarized, and the typical tunnel projects such as the Qincaitang, the Yanglin, and the Hutiaoxia underground interchange, the Fulong K15 shed tunnel, the Laoying tunnel, and the Maolipo tunnel are taken as examples. The innovative achievements and research progress of tunnel technologies such as multiarch and bifurcation, large deformation of soft rock, high seismic intensity, semihidden shed cave, and superlarge section are described. The development history of highway tunnel construction technology in Yunnan is reviewed, and the innovation and development of highway tunnel construction concept and technology in Yunnan in recent years are also discussed. Based on the development status of highway tunnels in Yunnan and the technical problems to be solved in the construction, operation, and maintenance, the shortcomings of highway tunnels in terms of poor geological treatment and mechanized construction of tunnel drilling and blasting, application of tunnel boring machine/shield construction, application of information and intelligent technology, preventive maintenance and equipment technology are point out. It is suggested that attentions should be paid to tunnel inspection, strengthening scientific maintenance and operation management of tunnels, service life extension, and service level improvement.

Key words: highway tunnel, multi-arch tunnel, soft rock large deformation tunnel, high seismic intensity tunnel, shed tunnel, largesection tunnel, tunnel ventilation
