既有桥梁的模糊综合评估分析-fuzzy comprehensive evaluation analysis of existing bridges
内蒙古科技大学硕士学位论文evaluation set of this bridge is (0.140, 0.293, 0.376, 0.171, 0.020), and then this bridge is in a quite poor state of the third type according to the maximum membership principle and weighted-average method. Results by both evaluation methods have been consistent, proving the applicability and effectiveness of fuzzy comprehensive evaluation method for bridge structure in this paper.Key Words:Assessment;Analytic hierarchy process;Fuzzy comprehensive evaluation; Weight;Yellow River Bridge目录摘要...................................................................................................................................IIAbstract ...................................................................................................................................
