摘　　要：在对比20m预应力混凝土空心板桥试验数据和理论计算数据的基础上,对计算模型铰缝连接刚度和桥面板刚度对荷载横向分布、挠度的影响进行了参数分析,对比了基频理论值和实测值,结果显示考虑铰缝和桥面铺装横向连接刚度的铰接板法得出的数据与实测值较吻合,仅考虑铰缝连接刚度算法可能导致检测评定结论出现偏差,结果可对空心板设计和后期检测维护提供一定的借鉴。On the basis of comparisons between experimental data and theoretical for 20m prestressed concrete hollow, the calculation model hinge joints connecting the and rigidity of the transverse load distribution, deflection parameters are analyzed, calculations results bridge deck stiffness and the theoretical value of the fundamental frequency and measured values are compared. The results show that the obtained data by hinging slab method is better matched with real measured value when considering hinge joints and the lateral connection stiffness of bridge deck, but only considering the hinge joints connecting stiffness detection algorithm may lead to bias conclusion. The results can provide a reference for hollow board design and later inspection and maintenance.
