- Abstract:
-
The frequent occurrence of geological disasters in the plateau and mountainous areas has caused great harm to the safety of important construction projects. Research on the susceptibility assessment of geological disasters on the proposed expressway has important theoretical and practical significance for the site selection and prevention of geological disasters in the later stag. Based on the analysis of the characteristics of current geological hazards, factors that contribute to the development of geological disasters were selected from four aspects:meteorological hydrology, topography, geotechnical type and structure, and human engineering activities. Based on GIS technology, combined with analytic hierarchy process (AHP) and information content model, we carried out the susceptibility assessment of geohazard for the proposed Shidian-Qingziqiao expressway.The assessment results were divided into high probable, mid-probable and low probable areas, the catalogues of existing geological disasters were used to verify the results, which indicates that the AHP_information model is highly operable in the assessment of the geological hazard susceptibility of the proposed project, and the reliability of the assessment result is high.
