The Experimental Study on Controlling the Hydration Heat Temperature Field of the Zhenyuling Bridge Pile Caps

Article Preview

Abstract:

Based on the experimental study into the temperature control scheme for mass concrete pile caps of the Zhenyuling Bridge, this paper did comprehensive research on effective ways to reducing massive concrete temperature caused by hydration heat, and preventing concrete cracks caused by thermal stress. The paper analyzed the effects of cooling pipe, concrete thickness and surface insulation materials on the temperature-stress field of massive concrete. By theoretical analysis and simulation research, the temperature control scheme was developed to guide the construction of massive concrete. Temperature-controlling techniques and precaution measures of early thermal cracks are introduced, which can provide reference to construction similar structure.
