Abstract

The Yang Pyeong bridge is high the occurred possibility of temperature crack by means of hydration Heat when the foundation of is constructed. Therefore, a pipe-cooling method was applied for reducing the temperature crack. Using the measured temperature curve when construction was carried out, the measured value and different facts were analyzed. In this paper, cause and analysis with respect to a mentioned above is to discuss firstly, and thermal characteristics of concrete and construction method hereafter is also discussed.
