摘　　要：本文在简要介绍混凝土结构裂缝普遍特征的前提上,详细探讨了超大尺寸混凝土结构和水工混凝土结构的裂缝成因及演变历程。着重阐述了混凝土结构裂缝的化学加固修复技术,包括电化学沉积修复技术、化学灌浆修复技术、氧化镁膨胀剂修复技术,并对今后混凝土结裂缝加固修复技术的发展提出了设想。The formation and evolution of cracks in concrete structures were briefly introduced based on the fundamental mechanism of cracks induced by individual loading,which had included cracks in supersize concrete structures and hydraulic concrete structures.The chemical reinforcements and rehabilitations to cracks in supersize concrete structures and hydraulic concrete structures were comprehensively discussed,which had included electrodeposition method,chemical grouting method,MgO expansive agent method.Eventually,tomorrow theoretical suggestions of cracks in concrete structures had been proposed.
