防止和减轻超长混凝土温度收缩裂缝的建议

On suggestions for prevention and reduction of temperature shrinkage cracks on super-long concrete

结合实践经验,分析了混凝土温度收缩裂缝的原因,从设计的角度进行控制,通过合理的使用后浇带、预应力结构及剪力墙,提高混凝土的抗拉强度,以减少混凝土的裂缝,提高建筑物质量。

By combining with practical experience, the paper analyzes reasons for temperature shrinkage cracks on super-long concrete, points out the control from the aspect of the design, and indicates that with the reasonable use of the late poured band, the prestressed structure and shearing walls, the tensile strength of the concrete will be strengthened, so the cracks of concrete will be reduced and the quality of buildings be improved.
