红船豆枢纽工程启闭机房框架梁裂缝分析与处理

Analysis and Treatment for Frame Beam Cracks of Hoist Room

混凝土建筑物在建筑与使用过程中,由于外载荷或变形等原因,经常会出现不同程度不同形式的裂缝.针对红船豆枢纽工程启闭机房屋面框架梁出现的梁侧垂直裂缝,分别从设计、材料、施工三方面分析了裂缝成因,进而提出裂缝修补方法,并对如何防止此类裂缝产生提出了预防措施,对类似工程提供了借鉴作用.

Concrete structure is likely to various cracks due to overload or transformation in the process of construction and operation. The problems of vertical cracks at frame beams of hoist room are analyzed in design,material and construction etc. Repairing methods are put forward and preventive measures of such cracks are also proposed correspondingly,providing reference for similar projects.
