摘　　要：基于王家河特大桥多塔斜拉桥,建立了桥梁BIM模型,通过轻量化和网页化形成了在线评估平台.基于江苏省地方标准《大跨径悬索桥和斜拉桥养护和评估规范》开发了多塔斜拉桥的评估系统,通过层次分析法确立了桥梁的评估指标.基于斜拉桥的健康监测数据,对索力等序列指标进行时间序列分析,提取了指标的趋势变化,并通过监测数据验证了预测方法的准确性,根据其趋势变化及上下限值对序列指标进行评估.通过BIM平台与评估体系的融合,为大跨度多塔斜拉桥服役性能评估提供了技术支撑.Based on the multi-pylon cable-stayed bridge of Wangjiahe River Bridge,a bridge BIM model is established.The online evaluation platform is formed through lightweight and webpage.Based on the local standard of Jiangsu Province of Long-span Suspension Bridge and Cable-stayed Bridge Maintenance and Evaluation Specifications,the evaluation system of multi-pylon cable-stayed bridge is developed.The bridge evaluation index is established through the analytic hierarchy process.Based on the health monitoring data of the cable-stayed bridge,the time series analysis on the sequence indicators such as cable force is carried out,and the trend changes of the indicators are extracted.The accuracy of the prediction method is verified through the monitoring data.The sequence indicators are evaluated according to the trend changes and upper and lower limits.The integration of the BIM platform and the evaluation system provides the technical support for the service performance evaluation of the long-span multi-pylon cable-stayed bridge.

关 键 词：BIM 多塔斜拉桥 桥梁评估 趋势预测
