On basis of the problems existing in the selection of the technical schemes and methods for tunnel construction, the author presents his comments: 1) The method of construction of long tunnels by means of driving from construction adits should be limited; 2) When the sequential tunnel construction method is to be adopted, various factors should be considered to reach scientific conclusions; 3) New Austrain Tunnelling Method (NATM) and mining method should be objectively defined and used. The author also expatiates on his above viewpoints in terms of theory and pratice. The paper can provide guidance for the technical persons in the field of tunnels and underground works in respect of updating their tunneling concepts, selecting more scientific and reasonable construction methods and making innovations in tunnelling technology.
