USE OF ANALYTIC HIERARCHY PROCESS METHOD FOR CLASSIFICATION OF ENGINEERING ROCK MASS

Analytic hierarchy process method is a kind of qualitative and quantitative analysis of multiplicate objective decision.Based on comprehensive analysis of multi-factors,the hierarchy structure system of engineering rock mass classification,which is constituted by four hierarchies,is established,because classification of rock mass engineering is affected by multi-factors.The paper gives in detail structure of judgment matrix of different hierarchy and process of classification.The example indicates that analytic hierarchy process method is simple,objective and effective.
