摘要
对某铁路既有钢筋砼简支T梁桥进行静、动载试验。从结构挠度、应变、动力系数以及横向振动特性四方面分析了桥梁结构在荷载作用下的实际工作状态,确定了桥梁结构的实际承载力,对该桥的强度、刚度进行综合评估。该试验为同类型铁路桥梁承载能力评定提供参考,为桥梁结构的维修加固提供依据。
The static load test and dynamic load test are carried on exiting RC simply supported railway T beam bridge.Based on strain,deflection,impact factor,dynamic properties,the working performance of the bridge is analyzed and the carrying capacity,stiffness and strength of the bridge are assessed. All these could provide references for carrying capacity evaluation and for strengthening the similar RC railway bridges.
