摘要
湖北恩来高速公路黄土坡1号隧道及陈家坡隧道位于地形地质条件较复杂的武陵山地区,该区存在溶洞、坍塌等常见不良地质灾害。黄土坡1号隧道及陈家坡隧道通过"加强支护、回填夯实、超前小导管注浆、疏排岩溶水"等施工技术,结合监控量测等信息反馈手段,动态指导施工,成功解决了溶洞冒顶突泥、大型溶洞及道坍塌等施工难题,顺利完成了隧道施工。
The Huangtupo No.1 tunnel and Chenjiapo tunnel of Hubei Enlai Highway locate in Wulin mountain area,the geological condition of this area is complex with karst cave and collapse.The treatment method with strengthening support,back-fill consolidation,small pipes for advance pre-grouting and drainage Karst cave water are adopted in Huangtupo No.1 tunnel and Chenjiapo tunnel with the monitoring,the construction difficulties are resolved.
