Grass Back Bridge Anchorage Mass Concrete Heat Of Hydration Analysis And Temperature Control Measures

With the vigorous development of China’s transport, mass concrete in bridgeengineering is more and more the temperature problem is more and more attention has been paid, a little mistake will crack, and some even cause structural damage. Mass concrete applications in hydraulic engineering more widely, many scholars have conducted research and made a lot of results, but these results are often not copy due to the difference of bridge engineering and hydraulic engineering.In this paper, on the basis of summing up the results of previous studies, try to collect instances of similar projects, with the help of finite element analysissoftware MIDAS/FEA Chongqing Fuling grass back of the Yangtze River Bridge in South Anchorage of the construction process simulation to get some useful conclusions, such as mass concrete temperature changes and the basic law ofthe internal and external temperature changes and concrete raw materials and co-ordination than the influence of the hydration heat, the temperature of the heat of hydration of concrete with the structural variation of the thickness of the layered pouring mass concrete hydration the impact of hot temperatures, and set a variety of conditions to analyze the influence of parameters on the temperature control, resulting in the effective temperature control measures.
