Abstract: The west to east gas pipeline project is a significant part in our national energy sources stratagem, landslide and mudflow hazards are well developed in Loess area, Jingbian to Yanchuan section, which are potential threaten to the oil-gas pipeline. In the article, Landslide is set as a case study, which is the main kind of geological hazards in this Loess area. Based on multiple remote sensing Information, the energy, distance from the pipeline and stability of the landslides are taken as evaluation indices, the geological hazard evaluation model for oil-gas pipeline in loess area are established, Practice shows that the model is right and useful.
