旧桥的病害检测与加固措施

Defect Inspection and Reinforcement Measures of Old Bridge

随着道路交通量的快速增长,重载车辆的不断增大,交通压力日趋严重,尤其桥梁作为道路的重要组成部分,因设计荷载偏低、环境影响、设计施工缺陷、运行压力、养护措施不力等因素,产生不同程度的病害,严重影响了桥梁的安全运营和正常使用。结合包头市乌拉山防洪沟桥的工程实例,介绍旧桥病害的检测方法、分析病害产生的原因以及制定加固措施。

With the rapid increment of road traffic volume and the continuous increment of heavy load vehicles,the traffic pressure is more and more serious. Especially the bridge as the important component of road has the different defects because of lower design load, environmental influence, design and construction defects, operation pressure, ineffective maintenance measures and etc. so as to seriously influence the safe operation and normal use of bridge. According to Baotou Wula Mountain Flood Control Ditch Bridge Project, the article introduces the defect inspection method of old bridge, analyzes the defect causes and formulates the reinforcement measures.
