摘　　要：桥梁静载试验是检测桥梁结构工作状态最直接、最有效的方法和手段。以实际工程为依托,通过变换试验车辆在桥面纵向位置以保证荷载效率在规定的范围内,挠度测点布置在具有代表性的梁底跨中截面处,选取反映桥梁设计的最不利受力状态,对公路桥梁进行上部结构静载试验,根据实测数据,对桥梁结构的技术状况、使用条件和承载能力进行评定。通过试验得出:主梁跨中截面竖向刚度、混凝土结构强度能够满足使用要求,个别主梁残余变形相对较大,弹性变形安全储备较低。The bridge static load test is the most direct, the most effective method and means for working state detection of bridge structure. Based on practical engineering, to ensure load efficiency within the prescribed scope through conversing test vehicle on the deck longitudinal position, needs to layout measuring point on the beam bottom midspan section, and choose the most unfavorable condition reflect bridge design, operation static load test for highway bridges superstructure. According to the measured data and results analysis, technical condition is evaluated, and the conditions and carrying capacity of the bridge structure are used. Through the test conclusion, main bridge midspan section vertical stiffness, and the strength of concrete structure can meet the requirements, when individual girder residual deformation is bigger, the elastic deformation safety stock is lower.
