| Abstract: | Based on analytical hierarchy process,the text expatiates process and approach of AHP in process of geological hazard evaluation of probability of occurrence,and establishes hierarchical structure model and judgment matrix.Consequently,the weight of factors of impacting geological hazard of probability of occurrence is ascertained,and the mathematical model of geological hazard evaluation of probability of occurrence of single and regional geological hazard.The approach is triumphantly applied in geological hazard evaluation of probability of occurrence in MianYang city,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. |
