Research on Sedimentary Microfacies Extension Identification Method Research Based on the Rough Set Theory
Meng Fan · 2013
The rough set theory is combined with the tunnel surrounding rock evaluation.The problem of weighting coefficient is converted into that of significance estimating on the attributes in rough set,and a relation data model about sedimentary microfacies division is established.By calculating the weighting coefficient of every division of the sedimentary,the authors evaluate the sedimentary by the extenics theory based on rough set.It is approved that the practical application shows,the sedimentary facies identification algorithm based on rough set theory has higher accuracy,which is an effective and potential method.The method also can be applied in such as basin type partition,lithology identification and other geological identification.
