When the mountain highway is along the river and mountain, the tunnel hole is affected by the mountain and mountain oblique. The portal section inevitably exist bias and shal ow buried, which lead to the dif icult into the hole. Half bright and half dark holed method has good adaptability to the oblique bias. This article introduces the construction sequence and the supporting method of half bright and half dark hole, in order to provide reference for similar projects.
