Abstract:

On basis of extenics theory the article adds thought of statistics and forms a method which based on extenics analysis of probability statistics. Being taken as examples of Yanbian Prefecture and Helong City project,  the appraisal stochastic elemnts are produced by means of simulating the corresponding factors for each object using Monte-Carlo in Matlab. Then the classical matter-element and extensional matter-element are set up for the stability of rock mass of slope and influence factor, and the possibility of objects are worked out by element and correlation function.  The Class of rock mass of slope are determined by the statistics of possibility,and hence some reasonable proposals are put forward. The possibility of object 2 belongs to class Ⅲ is 27 percent.Even though its maxium possibility belongs to the class Ⅱ, it can be kept safety that object 2 is defined as class Ⅲ because of existence of random sampling.

Key words: slope, extension, probability statistics, Monte-Carlo simulates, rock mass quality
