内蒙铁路运煤专用线圪秋沟工程滑坡勘察及治理

随着中国铁路的发展,在山区修建的铁路越来越多,往往由于对自然界的认识不足或工程活动不当引起诸多的地质病害,其中工程施工引起的斜坡体滑动时有发生,形成机理主要为:一是有发生斜坡滑动的地形,二是有产生的滑动的软弱面,三是降雨的影响,四是工程施工方法不当等。以圪秋沟工程滑坡为实例,针对其形成的原因,通过稳定性检算,采取清方减载、加强地表排水、反压、支挡等治理措施,避免滑坡对工程的影响。

The Survey and Control Measures on Geqiugou Engineering Landslide for Inner Mongolia Coal Transportation Railway Line

With the development of Chinese railways, railway construction in the mountains is increasing. Lacking of understanding of the nature or improper construction activities generated many geological disasters. Landslides caused by construction oeeured frequently. The formation mechanism mainly included the following aspects： first, the geology prone to slide; second, a weak surface to slide; third, the effect of rainfall; fourth, the inappropriate construction method, etc. Based on the example of Geqiugou engineering landslide, in view of its causes, the paper discusses ways to prevent the effects of engineering landslide on construction through measures like the stability check calculation, strengthening surface drainage, slope back pressure, retaining engineering and other control measures.
