基于程度分析方法的桥梁技术状况评定

Bridge Technical Condition Assessment Based on Degree Analysis Method

提出基于程度分析的桥梁技术状况评定方法。首先依据程度分析的置信区间试验法对桥梁构件指标进行评分,再建立指标体系并分配权重,最后采用分层加权的方法计算桥梁部件及总体技术状况评分。结果表明,该方法通过将数学模型与主观判断相结合,能够降低主观因素对技术状况评分结果的影响。

In this paper, the method of bridge technical condition assessment based on degree analysis is proposed. Firstly, according to the test method on the degree of confidence interval analysis of bridge component index score, and then establish the index system and weights, finally using method of hierarchical weighted calculation of the bridge components and overall technical score. The results show that this method can reduce the influence of subjective factors on the evaluation results of the technical condition by combining the mathematical model with the subjective judgment.
