ANALYSIS ON INFLUENCING FACTORS OF HYDRATION HEAT OF LARGE CAP IN FRIGID REGIONS
Temperature-induced cracks often occurs during the construction of large cap in frigid regions.Aiming at the construction of the main pier cap of a bridge in Qinghai province in winter,this paper studies the influence of external temperature,initial temperature of cooling water,diameter of cold-water pipe,and fly ash content on the hy-dration heat of cap by means of finite element simulation,which has significant effectiveness on the hydration heat of cap.We think the construction measures should be adopted to ensure the construction quality of cap.
