Construction requirements of various construction angles can be met, and design requirements of the whole machine can be met.

A construction method for unfavorable geology during tunnel engineering in high-altitude areas includes the following steps that (1) an advanced geological report is provided; (2) advanced supportingconstruction is carried out; (3) tunneling is carried out; (4) drainage treatment is performed for surge water; (5) initial supporting construction is performed; (6) after initial supporting is completed, grouting reinforcement is conducted at the position with large arch crown and haunch deformation; (7) a waterproof layer is laid on the surface of low-temperature concrete, and geotechnical clothis used for protection; and (8) an inverted arch and a second lining are constructed. According to the construction method, the damage degree and construction risks of unfavorable geology to tunnel construction are effectively reduced, construction safety is ensured, a large amount of precious experience is provided for high-altitude tunnel design and construction, and beneficial guidance and reference effects are achieved for tunnel design construction in high-altitude and alpine areas.
