隧道施工技术方案及方法遴选之我见

Comments on Selection of Technical Schemes and Methods for Tunnel Construction

针对目前隧道施工技术方案及方法选择中存在的问题,提出了:1)“长隧短打”应有所限制;2)隧道分部施工应全面考量,讲求科学;3)要客观定义、正确运用新奥法和矿山法等三个观点,并从理论到实践上作出了详细的阐述,对隧道与地下工程建设者更新观念,更加科学合理地选择施工方法,在技术创新上有所作为具有指导意义。

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 prati- ce. 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.
