| 摘 要： | 以某高速公路隧道工程为例，详细阐述隧道“零进洞”施工工艺要点，即在隧道进洞时采用超前管棚注浆等先进技术手段，通过利用超前管棚预支护，未开挖仰坡，未破坏原始地貌，成功实现了零开挖进洞，这为其他隧道工程的洞门施工提供了宝贵的经验。

| Abstract: | Taking some highway tunnel for example, the key points of ＂zero cave-entrance＂ construction technics are expatiated on in detail. That is, using the awning grouting in advance and other advanced technical method when excavating the tunnel. Through the use of the awning grouting in advance, the slope have not to be excavated, the primitive landform is not destroyed, thus the ＂zero cave-entrance＂ is successfully realized, which provide valuable experience for the entrance construction of other tunnel engineering. |
