摘要
在隧道施工中采用双连拱隧道可降低隧道线之间的间距,降低地形复杂侧隧道长度,降低工程施工成本,在山区隧道中应用广泛。中导洞施工作为隧道工程的关键环节,对隧道施工质量有非常大的影响。论文以实际隧道工程为例,对中导洞施工技术进行了分析和探讨,取得了良好的施工效果,为类似工程施工积累了经验。
In tunnel construction, double arch tunnel can be used to reduce the distance between the lines, reduce the length of the complex side tunnel, reduce the construction cost, and is widely used in mountain tunnel. The heading construction is the key link of tunnel engineering, has great influence on the quality of tunnel construction.Based on the actual tunnel project as an example, the heading construction technology are analyzed and discussed, and achieved good result of construction, accumulated experience for similar engineering construction.
