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

Abstract

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 out; compared with an existing bridge type selection method, the method has the characteristics of low dependence on decision makers, higher system reliability and low sensitivity to index misjudgment and evaluation errors.

Description

technical field [0001] The invention relates to the field of bridge comparison and selection, in particular to a bridge comparison and selection method based on a comprehensive index system based on typical environmental differences. Background technique [0002] The problem of bridge type selection has become a concern of the industry. Existing research work has conducted in-depth discussions on bridge type selection from different angles, and has achieved certain results, but there are still the following problems: ①The value of bridge type selection research and experience promotion for specific projects and regions is limited; ②Existing research The proposed evaluation index system for bridge schemes is not comprehensive enough, and some requirements of durability, post-maintenance cost, applicability and safety are often ignored; ③The index weights and evaluation results determined by subjective evaluation methods are mostly based on the judgment of a single decision ma...

Existing research work has conducted in-depth discussions on bridge type selection from different angles, and has achieved certain results, but there are still the following problems: ①The value of bridge type selection research and experience promotion for specific projects and regions is limited; ②Existing research The proposed evaluation index system for bridge schemes is not comprehensive enough, and some requirements of durability, post-maintenance cost, applicability and safety are often ignored; ③The index weights and evaluation results determined by subjective evaluation methods are mostly based on the judgment of a single decision maker In general, the evaluation results cannot avoid subjective randomness; ④The research on a specific index has a high reference value for the comparison and selection of bridge schemes, but any single index cannot be used as the only decisive index for the comparison and selection of bridge schemes. As a decision basis for bridge type selection

The above problems will limit the application and scope of the research results
