摘　　要：为检验预应力混凝土连续箱梁的设计参数和质量是否满足要求,论文对某桥的预应力连续箱梁进行了荷载试验,测试连续箱梁在作为渡槽及人行通行双重功能的荷载作用下其工作性能。试验的过程中运用了混凝土试块加载的方法,检验了连续箱梁的应力、挠度、基频和阵型,并和理论值相比较和研究,根据公路钢筋混凝土的设计规定,对该预应力连续箱梁做出质量评估。论文的评估方法可为同类型项目提供有益的参考。In order to check whether the design parameters and quality of the prestressed concrete continuous box girder meet the requirements,the paper carried out a load test on the prestressed continuous box girder of a bridge,and tested its working performance under the load as a dual function of aqueduct and pedestrian traffic.In the process of the test,the method of concrete test block loading is used to test the stress,deflection,fundamental frequency and array of the continuous box girder,and compared with the theoretical value,the quality of the prestressed continuous box girder is evaluated according to the design regulations of highway reinforced concrete.The evaluation method of the paper can provide useful reference for similar projects.
