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 multiarch
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.
