滑坡断裂带隧道进洞施工工法创新研究

Innovation of Tunnel Entry Construction Method in Landslide Fault Zone

滑坡断裂带隧道进洞施工工法以保神高速马桥隧道出口滑坡段为载体,采用深层土体位移监测技术,洞口地表局部注浆施工技术,洞口抗滑桩技术和长大管棚施工技术等创新工法,实现了安全快速进洞,为类似工程施工提供了借鉴经验。

In the Maqiao tunnel of Baoshen high-speed,four innovative methods are adopts:the deep soil displacement monitoring technology,the local grouting construction technology at the mouth of the tunnel surface,the anti-slide pile technology at the mouth of the tunnel and the long pipe shed construction technology.Through these innovative methods,realized the safe and fast access to the tunnel entry,which provides a reference for similar projects.
