为了进行连续刚构桥服役状态评估,建立了预应力混凝土连续刚构服役期状态模糊评估体系,确定了模糊评价标准集,给出了评价指标权重的计算方法,构建了适应连续刚构病害特征和评估指标体系的定量指标模糊隶属函数,提出了定性和定量评定相结合的定性指标隶属向量等级标准,使其更加具有地域和桥型适用性,与相关文献成果相比更加客观适用。
In order to assess the state of service of continuous rigid frame bridge, a fuzzy evaluation system of the state of service of prestressed concrete continuous rigid frame during service period was established. The fuzzy evaluation criteria set was determined. The calculation method of evaluation index weight was given. And fuzzy membership function of the quantitative index of the evaluation index system, and proposed a qualitative and quantitative evaluation of the subordinate vector grade standard, which makes it more applicable to the geographical and bridge type, which is more objective and applicable than the related literatures.
