Comprehensive index system bridge comparison and selection method based on typical environment difference

The invention discloses a comprehensive index system bridge comparison and selection method based on typical environment differences. The method includes the following steps: firstly, dividing the typical environments; then constructing an analytic hierarchy structure model, constructing a judgment matrix of each hierarchy, and calculating a weight; and then determining an evaluation standard and a scoring detailed rule, and finally performing evaluation and selecting an optimal bridge selection scheme according to an evaluation result. The invention provides a bridge type selection method for comprehensive indexes in a comprehensive index system based on typical environment differences, aiming at the problems of incomplete bridge type selection evaluation indexes, indefinite index weights, lack of objective evaluation standards, strong subjective experience dependence and high sensitivity to single index evaluation results at present. By adopting the method, bridge type selection can be effectively carried o
