Rock Integrity Evaluation Based on Fuzzy Element-Matter Model

Abstract:

Considering the characteristics of multi-factor control and ambiguity of rock integrity evaluation, single factor is only a reflection of the rock integrity from the full extent. This paper established a fuzzy matter element model for rock integrity evaluation, after a consideration of multiple evaluation factors, and the model is applied to the project in the literature [. The model is to be evaluated with rock integrity level as a matter element things whose features are the factors of rock integrity evaluation, combined with optimization principles to determine its corresponding fuzzy values, the composite fuzzy matter element is constructed, coefficient compound fuzzy matter-element is established by association transform correlation, by summing normalization method duplicate complex matter element is obtained, and association compound fuzzy matter element was established by adopting the computing model , finally by relevance sort rock stability evaluation results can be obtained. This model was validated by practical engineering and the result was reasonable and reliable. The result of this method was basically the same as literature [ and it has significant advantages in the calculation and analysis process.
