摘要
针对旧桥承载能力不足、通行能力低、支座破损等病害及混凝土缺陷等提出一些较成功的改造修补方法。其中针对承载能力不足的病害,提出了四种常见的上部构造补强方法;支座破损问题主要介绍固定支座及活动支座的改造、补强方法;对钢筋混凝土箱梁上层板易出现的局部缺陷和严重缺陷提出了几种修补方法。
In light of old bridge disease, such as inadequate load-bearing capacity, low traffic capacity, damaged bearing as well as concrete defects, this paper introduces some successful renovation and repair methods. It presents four common methods for superstructure strengthening in light of inadequate load-bearing capacity; introduces the renovation and strengthening methods for fixed and moveable bearings in light of damaged bearing issue.
