Concrete is a poor conductor of heat.In the large volume structure,it is easy to form a large internal-surface temperature difference due to the untimely dissipation of internal hydration heat,which can cause temperature cracks and affects the integrity and durability of the structure.In view of this,based on the engineering example and taking the roller compacted concrete double-curvature arch dam as the research object,this paper explores the analysis and implementation of temperature control standard through water cooling technology,aiming to control the internal-surface temperature difference and temperature drop rate of the concrete,suppress the occurrence of temperature cracks and improve the construction quality.
