隧道洞口施工地表预加固技术及应用

Stability Echnology and Application of Surface Pre-reinforcementin Tunnel Portal Construction

隧道施工时,隧道洞口是整条隧道的重要环节,通过隧道洞口的特点和标准的施工原则,在隧道工程建设中隧道洞口的施工是非常重要的,在施工时需进行隧道洞口地表预加固技术再施工。对隧道洞口岩性进行阐述,对地表预加固技术进行探讨研究。确定合理的施工方法,利用合适的隧道洞口地表预加固技术,确定隧道施工时的安全和质量问题,使工程快速高质量完成。

During tunnel construction,the tunnel opening is an important part of the entire tunnel.Through the characteristics of the tunnel opening and standard construction principles,the construction of the tunnel opening is very important in the construction of the tunnel project.Pre-reinforcement technology of the tunnel opening surface is required during construction perform construction.The lithology of the tunnel entrance is explained,and the surface pre-reinforcement technology is discussed and studied.Determine a reasonable construction method,use the appropriate surface pre-reinforcement technology of the tunnel opening,determine the safety and quality problems during tunnel construction,and make the project complete quickly and with high quality.
