高速公路小间距隧道施工技术浅谈

On construction technique of small spacing tunnel construction technique of expressways

主要介绍了广东博深高速公路水涧山隧道施工技术和工法,施工中顺利地解决了隧道线间距小、洞口段浅埋偏压严重等技术难题,在质量、安全、工期、成本等方面都取得了较好的效果,为以后相类似的小间距隧道工程施工提供一些借鉴和经验。

The paper mainly introduces the construction technique and the construction methods for Shuijianshan tunnel along Bo-Shen express- way in Guangdong, indicates the technical difficulties, such as the small spacing and serious shallow bias at the cave section, are solved in the construction smoothly, and achieves better-effect in the many aspects, such as the quality, the safety, the construction period, and the costs, and so on, so as to provide the reference and experience for similar and future small spacing tunnel projects.
