怀化分局所属枝柳铁路,在湖南省境内主要通过湘西高山地区,沿线开挖路堑边坡极多,自1983年元月交付临时运营以来,发生堑坡崩坍落石26次,其中2次被列车撞上,造成行车事故。因此,分析和治理岩石边坡失稳是路基工作的重要课题之一。自分局接管该线以来,对这些不良地质现象做了大量的整治工作,并取得较好的效果。现提出岩石斜坡破坏的三个实例分析及治理措施以供参考。
The branch Liuliu Railway belonging to Huaihua Branch mainly passes through the alpine region of Hunan Province in Hunan Province. There are many road cutting slopes along the route. Since the temporary operation was delivered in January 1983, collapsed rock falls occurred 26 times, of which 2 were hit by train On, causing traffic accidents. Therefore, the analysis and management of rock slope instability is one of the important topics of subgrade work. Since the branch took over the line, a great deal of remediation work has been done on these adverse geological phenomena and good results have been achieved. Now put forward three examples of rock slope damage and governance measures for reference.
