| 摘 要： | 2006年1月,承德韩郭线二级公路工程喇嘛梁隧道发生了大面积塌方。基于现场调查结果,详细描述了隧道塌方地段工程地质背景、与支护方法,以及塌方事故,并结合以上现场资料分析了该隧道塌方的机理;同时,还介绍了在该段塌方处理中如何采用的工字钢梁和超前注浆导管等技术手段。这一研究也为类似地质情况提供了宝贵的施工经验和理论支撑。

| Abstract: | During the construction of the Lamaliang Tunnel in Hanguo Road, a large scale of collapse occurred in January 2006. The collapse just happened in soft and hard rock joint area. Based on the investigation at the site, this paper discusses the I-beam and leading injected condulet which are adopted in a tunnel collapse treatment in hard and soft joint rock area, and sums up the construction experience, which may be useful for tunnel construction under similar wall rock condition. |
