Geological Conditions Such as Landslide( F p v K W en-kunAbstract ] In Mid-western China, the construction o f tunnels is inevitably required during the construction o f highways under
complex geological conditions, which poses a huge challenge to safe and smooth tunnel construction technology. Based on the geolog
ical conditions o f high and steep landslides at the entry section o f the flat ground spiral tunnel, the tunneling technology under the high
and steep landslide geological conditions is discussed, and comprehensive construction technologies such as adding anti-sliding piles,
grouting reinforcement o f mountain bodies, and follow-up o f long pipe sheds are proposed. The safe and smooth tunnel entry is ensured
through the application o f a series o f technologies, and reference for the tunnel entry construction in other similar high and steep land
slide geological conditions is provided.[Keywords ] spiral tunnel ; landslide ; bias voltage《4 f ?2 u4 f ???}%&?( ? ? ? u? ?
