紫下大桥的防腐蚀检测与评价

钢桥由于长期的暴露于腐蚀环境下,产生腐蚀和老化,影响大桥的美观,严重时影响大桥的正常运营和使用,甚至造成事故。紫下大桥运营四年来,产生一定程度的腐蚀,进行防腐蚀检测对合理的评价大桥的寿命年限,保证大桥的安全运营和道路的畅通是十分必要的。本文讨论了钢拱桥的防腐蚀涂层检测方法,并给出了检测实例,为既有钢拱桥的防腐蚀检测和评价积累了有益的资料。

Anticorrosion Inspect and Appraise of Zixia Steel Arch Bridge

Also the steel bridge produces corroding and aging, affects the bridge view, it is serious when affects the bridge the normal operation and the use, even creates the accident, because the long-time exposition under the corrosion environment. Zixia steel arch bridge come into being corrosion in a certain extent in course of use between four years by the reason of bridge corrosion environment cause. It is important that the bridge the security operation and the path unimpeded which of select suitable examination method and the instrument according to on the examination, appraisal bridge useful life. This paper discuss the anticorrosion inspect method of the steel arch bridge and deal with the Zixia steel bridge examination example. Meanwhile it is availability data increase to inspect and estimate steel arch bridge.
