Abstract: In order to promote the promotion and application of engineering technology and
innovative achievements in the construction of Yunnan highway tunnels, this paper summarizes
and summarizes the construction achievements of Yunnan highway tunnels over the past thirty
years. Taking typical tunnel projects such as Qincaitang, Yanglin, Hutiaoxia underground overpass,
Fulong K15 shed tunnel, Laoying and Maolipo as examples, this paper elaborates on the arch and
bifurcation, large deformation of soft rock, high seismic intensity, semi concealed excavation shed
tunnel The first innovative achievements and research progress in tunnel technology such as super
large cross-section were reviewed, and the development process of Yunnan highway tunnel
construction technology was reviewed. At the same time, the innovation and development of
Yunnan highway tunnel construction concepts and processes in recent years were discussed.
Based on the current development status of Yunnan highway tunnels, and in response to the urgent
technical problems in construction, maintenance, and operation, this paper points out the
shortcomings of Yunnan highway tunnels in the treatment of unfavorable geological conditions
through tunnel drilling and blasting, mechanized construction, TBM/shield tunneling application,
information and intelligent technology application, preventive maintenance and equipment
technology, and proposes that attention should be paid to tunnel inspection, scientific maintenance
and operation management of tunnels should be strengthened, and service life should be extended,
Suggestions for improving service levels; To provide useful references for the high-quality
development of Yunnan highway tunnels.
