Abstract
Taking the mass concrete of the main pier bearing platform of a super large bridge in an expressway construction project in Chongqing as the research object, the temperature field within 336 hours after the pouring of the bearing platform is numerically simulated and analyzed by using Midas FEA finite element software, the curves of temperature field with time when the inlet temperature is 10℃, 15℃ and 20℃ are emphatically analyzed. Through the finite element results, the law of hydration heat of cap is familiar, the temperature control scheme is determined and the reasonable pipe cooling design is carried out, so as to guide the construction. The results show that the temperature and crack control are more favorable when the inlet temperature of condensing pipe is 10℃.
