Evaluation of High and Steep Slope Stability Based on Theory of Extenics

A forecast method for the stability of high rock slope was proposed based on the matter element model as deduced from the theories of extenics. The elements in classical and sectorized field are defined using the stability classification and influence factors of rock slope, then an extendable forecast model for comprehensive evaluation of the classification of rock slope stability was established by the correlation function of matter elements and extendable sets. The forecast results were thus obtained through such evaluation. An exemplification shows that the method proposed can forecast the classification of rock slope quality more accurately and scientifically, thus providing a more reliable basis for taking economic and reasonable supporting/reinforcing measures in an open-pit mine which will be turned to underground mining.
