At the condition of natural cooling core,the Temperature field and Stress field of layer pouring of mass concrete in anchor-mound of certain yellow river supermjor bridge was analysised by fem simulation analysis of MIDAS/CIVIL.From analysis of the results,we can know the time and position of the highest temperature,the highest temperature,the maximum stress and the relevant allowable tensile strength.According to simulation results,we can know the position and distance of cooling pipe,and it provides theoretical guidance for the construction of supermajor bridge of mass concrete in anchor-mound.
