Abstract:Gravity anchorage is a typical massive concrete structure. The hydration heat during construction should be strictly controlled to avoid the temperature cracks. Taking the anchorage of Guojiatuo Bridge as an example, the hydration heat is analyzed out before construction and the corresponding temperature control measures for massive concrete are formulated. Through the field monitoring, all indexes meet the standard limits, and no concrete temperature cracks are found, which proves the efficiency of temperature control measures and ensures the quality of concrete.
