| Abstract: | In order to solve the problems of thermal stresses and temperature crack of mass concrete in the construction of large cable-stayed bridge,Yellow river Bridge No.3 in Ji＇nan was taken for example,prevention and control system of pre-numerical analysis and tracking monitoring was used to solve the cracking due to too large temperature difference between inside and outside during the construction of mass concrete,which provided experience for cable-stayed bridge in future. |
