塔里木河大桥一桥的病害调查及成因分析

Disease Investigation and Analysis of the Tarim River Bridge

通过对塔里木河大桥一桥的病害调查,以期得到产生病害的主要原因,以便为今后的大桥加固提供科学的理论依据。塔里木河大桥地处南疆阿拉尔市,长期自然环境的影响及外荷载作用,使其产生了裂缝、材料剥落等病害。利用桥梁无损检测技术对塔里木河大桥进行检测,得出产生桥墩梁病害的主要原因是由于盐渍土的腐蚀,而主梁则是由于长期的自然环境影响下的外荷载作用。

In order to get the main disease cause of Tarim River Bridge,The disease cause was investigated,so that to provide scientific basis for the future reinforcement of bridge. Tarim River Bridge is located in southern Xinjiang alar city,effects of long-term natural environment and external loading,to produce cracks,material spalling and other diseases. By using the Nondestructive detection technology to detect the Tarim River Bridge,Results shown： the main causes of diseases of bridge pier beam is the corrosion of saline soil,while the beam is due to external loads under the influence of the long-term natural environment.
