Study on Temperature and Stress of Hydration Heat of Mass Concrete in Arch Bridge Bearing Platform

Abstract

Through the simulation of finite element construction, the temperature and stress of hydration heat in mass concrete construction of arch bridge bearing platform were analyzed, and the necessity of setting condenser tube for temperature control was put forward. Based on the monitoring of the site construction of the mass concrete, the temperature and stress of the concrete under the corresponding temperature were obtained when concrete pouring into the mold, and were compared with the theoretical calculation data. Results showed the expected effect was achieved. Practice shows that the temperature control measures for the bridge are effective, and no concrete cracks were found in the mass concrete of the bearing platform. This has a certain reference and guidance for the construction of mass concrete of platform for the similar bridges.
