混凝土结构裂缝控制的工程实践

The Project Practice of Crack-control in Concrete Structures

混凝土结构的裂缝控制是关系到结构物能否满足正常使用要求的重要课题。本文讨论了筏基大体积混凝土施工的裂缝控制、混凝土长墙及核心筒周围板开裂原因,针对三个工程实例分别提出了裂缝控制对策,为类似的混凝土结构施工提供了指导性建议。

Crack-control in concrete structures is one of the important topics that impair structures' serviceability. This paper discusses the crack-control about the mass concrete of the raft foundation, and analyses the reason of cracks generating in the long concrete wall and in the concrete slab around the core cylinder. Then this paper dis- tributed the measures of crack-control for three project examples. This provides the guidance suggestion for construction of similar concrete structures.
