DHGF Theory Based on the Concrete Bridge Safety Evaluation Methods

Abstract

This paper to bridge safety evaluation as the starting point, the current evaluation method is based on the collection of the Delphi method, the level of analysis, grey cluster theory and the theory of fuzzy evaluation DHGF comprehensive evaluation method is applied to bridge safety evaluation, the establishment of a bridge safety evaluation of the DHGF evaluation model, and based on actual projects will DHGF evaluation method used in the actual concrete bridge safety evaluation, so as to verify the DHGF bridge safety evaluation of the scientific method, accuracy and operability. The main innovation is the first time DHGF evaluation theory is applied to bridge the field of evaluation and the establishment of the corresponding class bridge safety evaluation criteria and indicators in order to achieve the safety of the bridge accurate evaluation.
