摘要
黄土连拱隧道断面大、技术要求高、施工难度大,确定合理的施工方案和开挖方法,是确保隧道施工顺利实施的关键。结合我国第一座黄土连拱隧道——离石隧道,采用数值模拟分析,确定合理的施工方案,文中介绍施工过程及其重点难点问题,并根据全程监测结果,进行了分析,最后总结黄土连拱隧道施工的一些经验。
The construction of multi-arch tunnels in loess is complex and difficult. On the basis of the case of the first multi-arch tunnel in loess in China--Lishi Tunnel, the construction technology of it is discussed. The optimal construction scheme is determined by using the numerical simulation analysis. The key point in the construction is introduced in detail. The whole construction is monitored, and the monitoring data are analyzed. Then some conclusions on the construction technology are given.
