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。 The proper analysis and treatment of piers disease, the safety of the bridge. The disease of a bridge pier cap was introduced. The main reason of the disease was analyzed by alkali - aggregate reaction of concrete. According to the conditions produced by the alkali aggregate reaction, the treatment scheme of bridge pier platform using “excellent material to increase cross-section isolation method” was put forward, and the bridge was regained anew. The proposed bridge pier platform disease treatment program is correct, the treatment effect is good, similar to the pier analysis and processing with reference.
