某高速公路高架桥现浇连续箱梁过渡墩限位器处混凝土破损原因分析及对策

Causes Analysis and Countermeasures of Concrete Damage at the Highway Viaduct Cast-in-place Continuous Box Girder Limit of Transition Pier

高架桥现浇连续箱梁过渡墩混凝土破损是北方地区出现的一种桥梁病害形式,笔者现场进行认真细致地调查研究,结合当地极端气温条件、设计图纸、施工及检测部门的实地检测数据等方面,对过渡墩混凝土破损原因进行了全面梳理和分析,提出对策,可供同类工程参考借鉴。

The concrete damage of viaduct bridge cast-in-place continuous box girder transition pier is a form of the disease in the northern region. After investigation with local extreme temperature conditions, design drawing, and the test data provided by the construction and inspection department, the article analy-ses a highway cast-in-place continuous box girder viaduct bridge transition pier concrete damage, and puts forward countermeasures, which can provide reference for similar engineering.
