The Application of Unascertained Theory in Quality Comprehensive Evaluation of Bridge Engineering

Abstract

The Minneapolis bridge disaster that happened recently shows, our quality of science of bridge building taking quantitative index as main basis in use evaluates and has certain defects systematically synthetically at present, reflect the actual conditions in order to enable thinking the system can be true effectively, need to introduce into expert's system of judging, utilize its abundant experience to carry on the qualitative judgment to the bridge. This paper makes use of unascertained theory dealt with synthetically systematically to that the expert judge, the ones that avoided evaluating in the work are subjective and random, strengthen the scientific and objective fairness of evaluating the work, thus improve the authenticity of appraising the result.
