某拱桥加固后静力荷载试验

Static Load Testing and Analyzing of the Strengthened Arch Bridge

为了解小凌河大桥加固后的结构性能,对大桥进行了静载试验,测定了结构的强度和刚度,并将实测值与理论计算值进行对比分析,结果表明桥梁的工作状态符合设计要求,工作性能稳定。同时为以后桥梁的安全运营提供了必要的技术参数。

In order to study the structure behavior of the strengthened Xiao Ling River Bridge,the static loading test including deflection and strain are carried out under different loading cases. By comparing actual test with theoretical calculation, it shows that the actual working state of the bridge meets the need of the safe bearing capacity and using condition. The conclusions provide a necessary technical parameter for the bridge further using.
