某地铁站主体结构裂缝成因分析及修复技术

Cause analysis and repair technology of cracks in main structure of a metro station

某地铁站施工完成后,主体结构出现大量裂缝。通过对车站主体结构混凝土相关试验检测及施工资料核查,分析阐明了裂缝产生的主要原因。在对裂缝特征进行分析和对车站主体结构进行承载力验算的基础上,评价了裂缝对承载力的影响,并对不同裂缝提出了相应的处理方法。

After the construction of a metro station was completed,a large number of cracks appeared in the main structure.The main causes of cracks are analyzed and expounded through testing and checking the related test and construction data of the main structure concrete of the station.Then,based on the analysis of the characteristics of the cracks and the calculation of the bearing capacity of the main structure of the station,the influence of the cracks on the bearing capacity is evaluated,and the corresponding treatment methods for different cracks are proposed.
