考虑环境温度变化的大体积混凝土施工裂缝控制技术研究

Research on Crack Control Technology of Mass Concrete Construction Considering Ambient Temperature Change

一直以来,大体积混凝土温度裂缝的控制施工是一个难点和热点,在实际工程中需要对温度裂缝进行控制。本文根据江苏徐州九里山项目,分析了大体积混凝土温度裂缝产生的原因,考虑徐州地区温度变化特征,总结提出了大体积混凝土施工过程中控制有害温度裂缝产生的措施,并对环境保护提出了一些要求,该研究可在类似工程中指导施工,具有一定的工程意义。

For a long time,the temperature crack control construction of mass concrete is a diff icult and hot point,which needs to be controlled in practical engineering.In this paper,according to the JiuLiShan project in,Xuzhou,Jiangsu,analyses the causes of the mass concrete temperature crack,considering temperature variation characteristics of Xuzhou region,summarizes the process of mass concrete construction control measures of harmful temperature cracks,and puts forward some requirements for environmental protection,the research can guide the construction in the similar engineering,has a certain engineering signif icance.
