桥梁抢修保通难度评估研究

Difficulty Evaluation of Bridge Repair

着眼战时桥梁保障工作的实际需要,以桥梁抢修保通难度为评估目标,建立由桥梁结构复杂程度和周围环境条件组成的评估指标体系,并选用模糊层次分析法对桥梁抢修保通难度进行评估,最后结合某长江大桥进行实例应用,评估结果验证了方法的适用性。

Considering the actual demand of bridge support in wartime,the paper firstly establishes an evaluation index system which is composed of bridge structure complexity and surrounding condition. Then,it evaluates bridge repair difficulty with fuzzy analytic hierarchy process( FAHP). Finally,it verifies the applicability of the method through the example of a Yangtze River Bridge.
