摘要
以某工程桥面现浇板混凝土开裂事故为例,对混凝土开裂原因进行分析,指出环境温差、施工不当、细骨料(未过筛)是产生裂缝的主要原因;分析了裂缝对混凝土构件性能的影响因素,在此基础上针对不同宽度的裂缝给出了建议修补方案,为同类工程事故的处理提供了借鉴。
By analyzing the reason of concrete cracking in a frame structure slab, it is pointed out that the main reasons are influence of environment temperature difference, improper detailing measure and fine aggregate （ without sieve）. The influence of cracks on concrete members is analyzed and different measures are recommended to strengthen the cracking member. This article can give some reference for similar engineering accident.
