高速公路修建过程中,不可避免地要经过有地下采空区的地段。如何妥善处理这些地下采空区,消除地下隐患,是一件关系到高速公路未来安全运行的大事。山东东方路桥建设总公司在国道206线烟台~黄山馆高速公路修建中,亦遇到了同样的问题。我们根据具体问题具体分析区别对待的原则,通过进行实地勘测,选择了合理可行的施工处理方案,达到了令人满意的效果。烟台~黄山馆高速公路k2+484~k5+430区间.存在着多处因金矿开采而形成的地下采空区,且伴有巷道、竖井等。经调查.此路段自西向东共有7处互不连通的金矿采空区及巷道、10处废弃竖井。
During the highway construction, it is inevitable to go through the underground gob area. How to properly handle these underground mined-out areas and eliminate underground hidden dangers is a major issue that relates to the safe operation of the expressway in the future. Shandong Dongfang Road and Bridge Construction Corporation in the State Road 206 Yantai ~ Huangshan Museum Expressway construction, also encountered the same problem. Based on specific problems, we analyzed the principle of differential treatment, and conducted a field survey to select a reasonable and feasible construction treatment plan, which achieved satisfactory results. Yantai ~ Huangshan Hall Expressway k2 +484 ~ k5 + 430 interval There are many underground gobs formed by the gold mining, and accompanied by roadway, shaft and so on. After investigation, there are 7 gold mined-out areas and tunnels that are not connected with each other and 10 abandoned shafts from west to east.
