Evaluation of Slope Stability Based on Fuzzy Grey Element-Matter Model based on Properties of Mechanics

摘要

In view of the gray numbers in fuzzy matter-element values, in this paper matter element analysis which can consider the incompatibility between the various factors will be combined with gray system theory. Thus a fuzzy gray element evaluation model was established for the stability of rock slope, and the stability of Bu-zhao-ba open pit west slope was evaluated by this model. In this model the composite gray matter-element was established by five slope stability grades, six factors and its corresponding gray value by correlation transformation. This model can solve the above contradictions efficiently, and the result of the comprehensive analysis in the west slope of Bu-zhao-ba open pit by this model was same as the reality basically.
