| 摘 要： | 由于受工程地质条件、水文地质条件及人为因素等影响,隧洞洞口施工过程中易发生滑坡、塌方,往往造成难以成洞的被动局面.结合工程实例,对围岩破碎地段采取的洞口加固方案作了总结.该方案也体现了"新奥法"在隧洞工程中的实际应用.

| Abstract: | Due to geological conditions, hydrological and geological conditions and man-made factors such as the impact of tunnel cave construction process prone to landslides, often difficult into the passive situation, With practical examples, lots of broken rock cave reinforcement of the program are summarized. Meanwhile, the tunnel entrance reinforcement program reflects a "New Austrian Tunnelling Method" tunnel project in the practical application. |
