摘要
双侧壁导坑法是大跨径隧道施工常用方法之一.文中结合某隧道工程实例,详细介绍了双侧壁导坑法施工技术及其施工方案,并采用监测技术评估该施工技术的应用效果.结果表明,项目整体的实施效果良好,有效保证了隧道工程的安全性.双侧壁导坑法具有控制地表沉降、提升围岩稳定安全性的优势.
Abstract
The double-sided wall heading method is one of the commonly used methods for the construction of large-span tunnels.The article provides a detailed introduction to the construction technology and plan of the double-sided wall heading method,combined with an example of a tunnel engineering project,and evaluates the construction effect of this technology using monitoring technology.The results indicate that the overall implementation effect of the project is good,effectively ensuring the safety of tunnel engineering.The double-sided wall heading method has the advantage of effectively controlling surface settlement and improving the stability and safety of surrounding rock,and the future engi-neering application market is broad.
