摘　　要：某工程由于预拌混凝土质量问题引起基础局部混凝土强度达不到设计要求,须停止上部结构施工进行基础加固处理。对加固部分基础采用钢支撑托换,凿除承台、地梁及底板混凝土,钢筋替换后重浇混凝土。加固期间加强监控,解决了质量事故问题,保证了上部继续施工。quality defects reinforcement. platform, concrete. In a foundation project, local concrete strength fails to satisfy the design requirements due to of commercial concrete, and superstructure construction must be stopped for foundation Steel support, pinning is adopted in the foundation where needs to be reinforced. Bearing ground beam and bottom plate concrete are chiseled and steel bars are replaced before re-pouring of Monitoring is strengthened during reinforcement to successfully solve quality accident and guarantee continuous construction of superstructure
