Abstract

By combining the two methods of AHP (Analytic Hierarchy Process) and Fuzzy (Fuzzy Comprehensive Evaluation Method), this paper processed the evaluation of geological hazard susceptibility of Zhongwu pipeline. First of all, according to the geographic background and running situation of Zhongwu pipeline, the area which Zhongwu pipeline pass is divided into 72 regions. Secondly, the paper establishes a hierarchical structure model and judgment matrix, and calculates the weight of geological hazard probability Index by AHP. Thirdly, the paper calculates the membership degree based on fuzzy comprehensive evaluation method, and achieves geological hazard susceptibility partition of Zhongwu pipeline. The result indicates that the method is reasonable and effective. At the same time, the evaluation result has upper precision and greater fitting degree than 90 percent. Finally, combining Medium-Range or Long-term Weather Forecast and the information of pipeline to achieve Long-term geological hazard warning is discussed.
