| 摘 要： | 清绿直线黑河1#桥建成于1958年,经过多年的通车运营后,经检查发现主桥结构出现了多种缺陷,严重影响了此桥的正常运营。分析了桥梁产生的缺陷,并提出了针对该桥的加固技术,利用ansys有限元分析软件对加固后钢桁架简支梁的运营状态进行模拟,分析了桁架的内力变化和动挠度,希望能为其他类似桥梁的加固提供借鉴。

| Abstract: | Green line 1# Heihebridge was built in 1958, after several years of operation, the main bridge structure have found many defects through the inspection, has seriously affected the normal operation of the bridge. This paper analyses defects of bridges, and put forward the reinforcement technology of the bridge, have simulated the steel truss beam of the operation state of consolidated by use of the finite element analysis software ANSYS, analysis the changes of internal forces and dynamic deflection, hope for other similar bridges reinforcement for reference. |

| Keywords: | defect reinforcement technology changes of internal forces dynamic deflection |
