关于防止水工混凝土裂缝的探讨

Study on Preventing Crack of Hydraulic Concrete

文中从混凝土的力学和热学物理性能出发,探讨了水工混凝土裂缝发生的原因,分析了保证基础块混凝土不产生贯穿性裂缝和表面裂缝的条件,在工程实践基础上,总结了提高混凝土抗裂能力的方法及防止裂缝的结构措施和施工措施。

Starting from the physical performance of mechanics and heat of concrete, this paper probes the formation cause of crack in hydraulic concrete and analyzes the condition under which the result that the transverse and surface crack do not appear in concrete of foundation block is ensured. On the basis of project practice, this paper summarizes the method to raise crack-resisting capacity of concrete and discusses the structure and construction measures to prevent crack.
