| 摘 要： | 桥墩病害的正确分析处理,事关桥梁的安危。介绍了某桥墩承台病害,分析了产生病害的主要原因是混凝土碱骨料反应。据碱骨料反应产生的条件,提出了桥墩承台病害采用优料加大截面隔绝法的处理方案,经由实施,使桥梁重获新生。所提桥墩承台病害处理方案正确,处理效果良好,对类似桥墩的分析处理具借鉴意义。

| Abstract: | The correct analysis and treatment of pier cap problem affects the safety of bridges.In this paper,a project of pier cap problem was introduced,and the reason for the problem was analyzed.The results show that the main reason of the pier cap problem is the concrete alkali-aggregate reaction.According to the conditions of this reaction,the isolation with good material and increase of cross-section treatment scheme is put forward for the pier cap problem,and it makes the bridge rehabilitation.The treatment of... |
