摘要: 对我国隧道工程及施工技术现状、取得的成就及发展趋势进行了分析,介绍了21世纪初将要建设的特长和特殊隧道工程,分析了隧道工程的特点,指出要完成必须具备的基本条件.采用"新奥法"原则的矿山法需要提高开挖成洞速度,降低工程成本,改善施工作业环境条件和安全技术.隧道掘进机和盾构施工方法具有施工速度快、隧道成型好、机械化强度以及周边环境影响小等显著优点,将是新世纪广泛采用的一项新技术.沉管隧道在我国也将逐渐得到应用.Abstract: This paper focus on the current state, achievements and tendency of tunnel engineering and its construction technique in China. Some planning tunnels engineering projets in the beginning of 21st century were introduced. The characteristics of the super-long tunnels and some special tunnels were mentioned and basic conditions necessary to build these tunnels have been prsented. It will be necessary to increase the excavating speed, reduce building cost and improve environmental condition and safety technique for New Austria Tunneling Method. Tunnel boring machine and shielding machine, being of the advantages such as rapid construction, good shaping of tunnel section, less environmental effects and so on is a advance technique in the 21st century. The submerged tube tunneling method will be gradually used.
