摘　　要：通过静载试验测量结构受力部位的挠度、位移和应力变化;通过动载试验,掌握桥梁结构的动力特性,了解桥梁对动载激励的总体反应,判断桥梁的总体结构刚度和内在力学特性,为桥梁的安全使用提供依据;通过静、动载试验研究和理论计算分析,评定桥跨结构实际承载能力,工程的可靠性,以及在实际使用荷载下的工作性能;为桥梁的使用、维修和管理提供依据。In the paper, the static load test is used to measure the deflection of structure stress position, displacement and stress changes through; the dynamic load test is used to understand the dynamic characteristics of bridge structure and the overall reaction dynamic excitation and judge the overall structure of the stiffness of the bridge and the mechanical properties to provide the basis of safe use for the bridge;the static, dynamic load test study and theoretical analysis are conducted to evaluate the bridge structure actual bearing capacity and engineering reliability in actual use and its performance under load. It provides the basis for the use and the repair and the management of the bridge.
