On the crack problems of mass concrete

分析了收缩裂缝和温差裂缝产生的原因,并对其防止措施进行了阐述,指出大体积混凝土的施工除了按设计要求施工外,更应重视对现场施工过程及施工工艺的控制,采取有效的措施才能降低大体积混凝土产生裂缝的几率。

It analyses the reasons of the generation of shrinkage crack and difference in temperature crack,represents the prevention steps,points out that the construction of mass concrete should think much of the process of field construction and the control of construction technique and adopt the effective steps to decrease the ratio of crack generate of mass concrete except construction obey the request ion of construction.
