摘要
中山顶隧道地质勘察评估为Ⅰ级风险岩溶隧道,是广乐高速公路建设的控制性工程之一。根据中山顶隧道的岩溶特点,就施工过程中3个典型岩溶处治设计方案进行介绍,并总结岩溶区大跨隧道设计经验,以期对类似工程的处理起到抛砖引玉的作用。
According to survey and evaluation, Zhongshanding Tunnel is a karst tunnel at level I risk, and one of control projects in construction of Guangzhou-Lechang Expressway. In accordance with karst features in Zhongshanding Tunnel, this paper introduces three typical design schemes for karst treatment during construction, and concludes experiences on design of large-span tunnels in karst area with a hope of throwing a sprat for treatment of similar project.
