Abstract

Abstract

Taking a subway station project in Shenzhen, Guangdong Province as the research object, temperature measurement test was carried out on the mass concrete of three side walls. The characteristics of concrete temperature changes under different ambient temperatures and different weather conditions were analyzed, ABAQUS finite element software was used to simulate the temperature rise process of concrete. The data obtained by the test were fitted by changing the ambient temperature conditions. The results showed that the ambient temperature had a great influence on the peak, heating rate and cooling rate of concrete temperature, and the radiant heat transfer coefficients of concrete surface would be greatly different between sunny and rainy days when performing finite element simulations, the study could provide technical support for pouring and crack control of mass concrete.
