Post-doctoral Research Center, China Tiesiju Engineering Group Co. , Ltd. , Hefei 2e002e, China;2. The Second Engineering Co. , Ltd. , China Tiesiju Engineering Group, Suzhou 2151e1, Jiangsu Province, China)Abstract: Based on multi-objective optimization theory, according to analysis result of finite elementmodeling, after determining the optimization objectives, this study proposed a layout method with goodcooling effect for the cooling water pipes of mass concrete. This method was adopted in the construction ofbearing platform of main pylon of the Yongjiang River cable-stayed railway bridge; and the temperaturemonitoring results showed that the temperature v
