| 摘 要： | 应用新近发布的JTG/T J21-2011公路桥梁承载能力检测评定规程中荷载试验评定方法评估某公路桥梁承载能力,通过动载试验获得桥梁固有频率,修正有限元模型,然后将静载试验实测挠度、应变与理论计算值对比得出校验系数,最终评定桥梁承载力,为桥梁检测提供了理论依据。

| Abstract: | The paper evaluates the highway bridge bearing capacity according to the loading test evaluation methods recently issued in JTG/T J21-2011 Highway Bridge Bearing Detection and Evaluation Regulations.It obtains natural bridge frequency with dynamic loading test,modifies the finite element model,and then obtains the verification coefficient of actual detecting reflection,strain and theoretical calculation value of static loading test,and finally assesses the bridge bearing capacity,which has provided theoretical basis for bridge detection. |
