摘要
针对黄陵矿业公司运煤铁路专用线新庄科隧道西出口边坡崩塌、落石灾害发育的特点,提出采用喷射砼面层防止岩层表面进一步风化、采用预应力锚索框架梁防止山体发生崩塌灾害的治理设计方案,并根据设计对边坡进行了治理施工。介绍了治理方案设计及施工要点。
According to the slope collapse and rock falling in a tunnel of coal special railway line in Huangling mining com- pany, the control plan was put forward by concrete spraying and pre-stressed cable frame beam to prevent the further weath- ering of the rock surface and the mountain collapse. The control construction was carried out based on the design the paper introduces the control plan design and the main points of the construction.
