In vation method and combination of engineering practice, comparison and selection of schemes between cover - exca- open - cut method is conducted and design points and construction technology of cover - excava- tion are introduced. Research shows that cover - excavation method can heavy excavation at tunnel portal section at the same time so as to protect ensure the stability of massif and avoid ecological environment.
