大体积混凝土温度裂缝控制措施与监控分析

Control measures and monitoring analysis of temperature cracks in mass concrete

从施工材料控制、施工过程措施控制两方面阐述了施工温度控制措施,介绍了采用布设降温冷却水管防止裂缝的效果分析,并通过实测温度变化理论计算温度应力来验证大体积混凝土的抗拉安全稳定度,以达到控制裂缝产生,保证工程质量的目的。

From two aspects： material control and construction process control measures for construction temperature control are elaborated. The effect of setting cooling water pipe to reduce the temperature is analyzed. Based upon temperature change theory and measured data the temperature stress is calculated to test the safety stability of concrete in order to reduce the production of cracks and ensure engineering quality.
