摘 要：As one of the major problems of geo-engineering,landslides often influence the safety of linear engineering projects that cross mountainous ***,when selecting suitable routes for such projects,it is important to assess their susceptibility to *** this paper,we used a natural gas pipeline in the northeast of the Yunnan-Guizhou Plateau of China as a case study to analyze landslide *** on engineering geological analogy,the analytical hierarchy process,and the least-squares method, a regional landslide susceptibility assessment model was developed and was programmed using GIS ArcEngine components under the Visual *** *** landslide susceptibility along the Zhong-Wu natural gas pipeline from Zhongxian County to Wuhan was assessed based on this model and classified into five levels:very safe,safe,moderate,susceptible,and very susceptible. The high accuracy and prediction capability of the model were confirmed by comparing the model results with past landslide data and performing a prediction *** results indicated that the assessment model used in this study is reliable and can be used for landslide susceptibility assessment and route selection in other areas.
