| 摘 要： | 西气东输管道工程全长4000余公里，沿线共发育155处滑坡，其中有17处滑坡不稳定。这些不稳定滑坡主要分布在宁陕段和山西段，以小型浅层黄土滑坡和堆积土滑坡为主。它们的形成主要与所处地段的地形地貌、岩土性质有关，同时还受河流冲刷、人为因素的影响。它们对管道自身安全产生威胁，同时也会破坏管道附属设施。这些不稳定滑坡的防治措施主要有抗滑挡墙、修整坡面和防水。

| Abstract: | The gas pipeline from west to east in China exceeds 4000 km. There are 155 landslides along the pipeline. But only 17 landslides are unstable. Most of the unstable landslides are located in Ningxia, Shaanxi and Shanxi which are shallow loess landslide and deposit landslide. The formation mechanism of the unstable landslides include the landform and physiognomy, stratum lithology, river erosion and man-made factors. The danger to the pipeline and its attached facilities are researched. The countermeasures of prevention and treatment are proposed, such as anti-slide retaining wall, slope leveling and waterproofing. |
