| 摘 要： | 扁河桥为预应力混凝土连续箱梁桥，为检验扁河桥的实际承载能力，对该桥进行了静载试验分析。静载试验采用加重车辆加载，在试验过程中，对各个加载工况进行挠度和变形观测，并将实测值与设计理论计算值进行对比分析，试验分析结果表明：该桥实际结构的强度和刚度均满足设计要求，实测残余变形满足小于20％的要求，可以交付使用。

| Abstract: | Bianhe bridge is a continuous box girder,it was tested with static loading for its bearing capacity.The loading test was loaded by the vehicle,the deflection and deformation of the bridge was observed in the test.The test result indicated the stiffness and the strength of the bridge structure could meet the need of the design and the residual deformation could meet the need of less than twenty percent,the bridge can be open to traffic. |
