Fuzzy Mathematics Analysis for the Survey Result of Large Span Continuous Box Girder Bridges' Common Quality Defects

Abstract:

The essay was initiated by Hubei Provincial Communications Department, endorsed by Traffic Planning and Design Institute of Hubei Province, Bridge Science Research Institute (China Zhongtie Major Bridge Engineering Group), Huazhong University of Science and Technology, Wuhan University of Science and Technology. 6 kinds of common bridge diseases and 6 kinds of effective improvement measures were ranked and graded using questionnaire, and counted and calculated the weight using dual contrast fuzzy decision method. The calculation result shows that the concrete crack, bridge damage and main girder downwarping were accounted for larger proportion in the current common bridge diseases. In improvement measures, strengthening bridge linear control, mastering the concrete ages and strengthening dual control of prestressed reinforcement are particularly important.
