摘要
岩溶作为不良地质条件对隧道施工造成较大危害,溶洞的存在影响围岩压力、支护结构受力和施工安全性。以某隧道工程实例作为研究背景,文章深入分析了公路隧道岩溶施工技术的施工方法,分别从溶洞施工方案确定、施工准备、溶洞开挖、支护施工以及锚杆支护多方面对公路隧道岩溶施工技术进行研究,实践可知,通过隧道岩溶施工技术的应用,能够切实提高隧道工程的掘进速度和质量,对促进公路事业有重要作用。
Karst as a bad geological condition has caused great harm to tunnel construction.The existence of karst cave affects surrounding rock pressure,support structure stress and construction safety.Taking a tunnel engineering example as the research background,the construction method of karst construction technology of highway tunnel is deeply analyzed,and the karst of highway tunnel is determined from the construction scheme of karst cave,construction preparation,karst excavation,support construction and bolt support.The construction technology is studied.It can be seen from practice that through the application of tunnel karst construction technology,the tunneling speed and quality of the tunnel project can be effectively improved,which plays an important role in promoting the highway industry.
