Abstract Error prediction and adjustment as well as reasonable construction option and organization will be concerned with before and after tunnel breaking through. In addition, it is very complex for the structure at the tunnel breaking-through section. Especially in soft rocks, it is very often to have large convergences and deformations and cracking in primary support before and after the breaking-through of tunnel, liable to result in collapse. The key points of construction before and after the tunnel breaking-through are presented in the paper by taking the construction of tunnel group at Lot I of Lanzhou-Chongqing railway as the background.
