| 摘 要： | 跨径136米的石潭溪大桥加固方案采用在吊杆横梁之间加设钢管桁架加劲纵梁。提高了桥道系的整体刚度,改善车辆通过桥面时的振动性能。在活载作用下,吊杆受力更加均匀。通过有限元加载计算分析,表明该桥加固前后均能满足新规范的荷载等级要求。

| Abstract: | A project is used in the reinforcement of Shitangxi Bridge(136m span) by adding CFST truss longitudinal beam between transverse beams of suspender.This project can enhance the whole rigidity and improve the vibration performance.Furthermore,the force in suspenders will be increasedly even under the live load.Through calculation analysis on FE(finite-element) loading,it is indicated that this bridge can satisfy all of the load grade of new code whether before or after reinforcement. |
