摘要
本文是根据南水北调西线工程超前期工作任务的需要,围绕国内外长隧洞工程实例的修建概况、特点及遇到的复杂地质问题进行的专题情报调研综述。调研资料表明,尽管长隧洞的特点是工期长、造价高、施工难度大,但近年来在勘测方法、施工技术、掘进机的应用等方面有明显的进展,可供国内借鉴参考。
A review of information investigation on long tunnel engineering, its construction work, characteristics and the geological problems encountered both abroad and at home is given. The long tunnel is characterized by long duration of construction, high cost and difficult work. The progress in survey, construction technology arid application of boring machine are introduced.
