静载试验在桥梁检测内力分析中的应用

以某大桥为研究对象，通过测定桥梁试验孔控制截面在试验静荷载作用下的应力，并与理论计算值比较，检验桥梁实际结构控制截面应力是否与设计要求相符。根据试验结果，该桥试验孔各测点实测应力与理论应力相比，校验系数均小于1．0。说明试验孔结构强度满足设计要求。

Application of Static Load Experiment in Analysis on Internal Force of Bridge Testing

Taking a bridge as an example, this paper detects the stress in test of static load of bridge test hole control section, compared with theoretical calculation, and judge if the test stress is consistent with the de- sign requirements. According to the test results, the check coefficient of test stress is smaller than 1.0, which shows that the test hole structure strength meets the design requirements.
