大体积混凝土温度裂缝控制综合措施

Comprehensive measure of mass concrete temperature cracks control

分析了大体积混凝土温度裂缝的形态及原因,阐述了大体积混凝土的定义及其温度裂缝控制的基本方法,并结合具体工程实例研究了大体积混凝土温度裂缝控制的综合措施。强调大体积混凝土裂缝控制要想取得好的效果,必须“抗”与“放”结合,从多方面考虑,采用综合措施。

This paper analyzes the form and cause of the mass concrete temperature cracks and expound the definition of mass concrete and basic methods of temperature cracks control of mass concrete. Moreover, the comprehensive measure for mass concrete temperature cracks is discussed through a project example. From this paper, it is emphasized that we should use comprehensive measure to control mass concrete temperature cracks and consider it from many aspects with the principle of combination of ＂to resist＂ and ＂to release＂, if we want to gain good effect of mass concrete temperature cracks control.
