中文摘要:
      针对桥梁损伤评估中目标和影响因素的模糊性,应用模糊数学中的模糊综合评估方法,通过建模、分级,确定各级因素域及权重,得出各级评价向量,定出桥梁整体结构损伤度。最后根据最大隶属原则和非对称贴近度法等两种方法评估出桥梁损伤等级。从应用于大庆市庆虹桥的实际检测评估中证明,此评估方法是合理可行的。
英文摘要:
      Aim at bridge damage assessment the vagueness of goal and influencing factor, the fuzzy synthesize assessment method in fuzzy mathematics is applied ,through building model, grade, determine different levels factor region and weight, reach different levels appraisement vector . Bridge overall structural damage degree is decided. Final basis is the biggest subordinate principle and asymmetrical keep close degree law two methods to evaluate bridge impairment scale. Since application the actual assessment of Qinghong bridge in Daqing city proves that this assessment method is reasonably feasible.
