Diversion tunnel safety assessment method and system based on ANP-entropy weight theory cloud model

Abstract

The invention provides a diversion tunnel safety evaluation method and system based on an ANP-entropy weight theory cloud model, and relates to the technical field of hydraulic tunnel structure evaluation, and the method comprises the steps: constructing a hydraulic tunnel health diagnosis index system; subjective weighting is carried out on the diagnosis indexes through a network analytic hierarchy process, the diagnosis indexes are quantified to construct a judgment matrix, and the judgment matrix is calculated to obtain subjective weights; objective weighting is carried out on the diagnosis indexes through an entropy weight method, a normalized matrix of the diagnosis indexes is constructed, the index value proportion and the index information entropy are calculated by using normalized index data, and objective weights are obtained; fusing the subjective weight and the objective weight to obtain a comprehensive weight, and constructing a comprehensive cloud evaluation model based on the comprehensive weight; according to the method, a good basis can be provided for maintenance and reinforcement in the tunnel operation period.
