Temperature Field Simulation Of Mass Concrete In Cold Regions And Study Of Temperature Control Measures

In cold regions, the cement hydration heat causes the concrete interior temperature to elevate rapidly, casting together with bad weather, open-air service environment, their poor thermal performance, irregular crack often appears on the surface, finally become surface crack. Researching temperature field change rules of local climate and taking reasonable temperature control measures to prevent the cracks, become important means. While the traditional experiment methods of gaining parameters have cannot meet the requirements in accuracy and time accumulation characteristics. a new platform were provides by some intelligent algorithm.In order to acquire the thermal parameters according with the actual engineering by monitoring data, analyzes entity component temperature changes on different conditions and different anti-cracking measures effect, this paper mainly do aspects of work as following:(1)The environmental temperature changes expression in the northeast of China were got by fitting the monitoring results. The study provided reference for the research of the mass concrete temperature changes in this area, enriching the existing researches.(2)The mass concrete-structure analysis model of the thermal parameters was built in this paper. This attempt opened up a new platform for the ant colony algorithm in civil engineering application, with high practical meaning and theoretical significance.(3)The effective measures to control the temperature were given by studied the temperature field distribution of the mass concrete structure and its changes over time, for the purpose that ensures the safety of the high-speed railway service life and provides theoretical support.
