| 摘 要： | 岩溶突水是山区隧道和矿山巷道工程建设中常见的地质灾害之一。某隧道建设工程为深埋岩溶隧道,隧道大部经过碳酸盐岩地区,局部发育软弱夹层,地质条件复杂程度和施工难度较大。文章通过对工程实例进行分析,并结合地质条件,建立一个以开挖面为隧道边界的纵断面地质模型,然后运用FLAC程序进行数值建模,模拟研究,得到一个岩溶突水形成、发展、发生的过程,初步揭示了该隧道岩溶突水的规律及特点,对类似地质条件的工程建设具有借鉴意义。

| Abstract: | Tunnel water gushing is a eommon geological disaster of mountainous areas and mine laneway construction. A certain construction project locates in the deep-berry tunnel, most part of the tunnel in the carbon earbonatite area, with week tier, making it difficult for geological construction. The project is meaningful as it analyzes the project examples with local geological conditions, establishes a module of vertical section with digging interface as the broader, uses FLAC program for establishing data module for monk research, acquires a process of formation, development and making up of a rock lava, discloses the feature of water gushing. |
