| Abstract: | This paper mainly introduces highway and railway combined bridge of the yellow river in zhengzhou about temperature control technology of concrete construction, analysis 1/4 structure model by the method of finite element, and simulate flow of the different cooling water tube for concrete internal effects of the hot water needs. By comparison with actual conditions, it is good, which put forward the settings form and the optimized technological measures of temperature control cooling tube in mass concrete construction, and provides basis for concrete temperature control technology in crack. |
