摘　　要：为了探索独塔钢-混组合梁斜拉桥的整体受力特征,验证其整体刚度以及承载性能是否满足设计目标预期,以聊城市经济技术开发区中华路徒骇河大桥工程为依托,对主桥进行静载、动载试验。试验结果表明,中华路徒骇河大桥主桥结构状态良好,其整体刚度及承载能力均满足设计规范对于城-A级荷载等级的要求。In order to explore the overall stress characteristics of the single-tower steel-concrete composite beam cable-stayed bridge,and verify whether its overall stiffness and bearing capacity meet the design goal expectations,based on the Tuhai River Bridge Project on Zhonghua Road,Liaocheng Economic and Technological Development Zone,the static and dynamic load tests are carried out on the main bridge.The test results show that the main bridge of Tuhai River Bridge on Zhonghua Road is in good condition,and its overall stiffness and bearing capacity meetthe requirements ofthedesign codefortheurban-A load level.
