杭州湾跨海大桥钢箱梁桥面铺装病害分析与预测

Disease analysis and prediction of steel box girder deck pavement of Hangzhou bay bridge

对杭州湾跨海大桥钢箱梁桥面铺装进行病害调查与统计分析,通过ANSYS建立力学模型,分析钢桥面铺装病害产生原因;结合钢桥面铺装养护历史、历年检测数据和累计交通量数据,得到杭州湾跨海大桥钢箱梁桥面铺装PCI预测模型。

Based on the investigation and statistical analysis of the diseases of steel box girder deck pavement of Hangzhou bay bridge, the mechanical model is established by ANSYS to analyze the causes of the diseases of steel bridge deck pavement. The PCI prediction model of steel box girder deck pavement of Hangzhou Bay Bridge is obtained by combining the maintenance history of steel bridge deck pavement, the inspection data over the years and the cumulative traffic volume data.
