大直径钢管混凝土桥塔的温控防裂研究
Research on Temperature Control and Crack Prevention of Large-diameter Concrete Filled Steel Tubular Bridge Tower
摘要
Abstract
In order to study the effective temperature control and crack prevention measures of large-diameter concrete filled steel tubular(CFST)bridge tower,a finite element analysis model based on Ansys.The research evalu-ated the effect of common concrete pouring at low-temperature,special concrete pouring at normal-tempera-ture and special concrete pouring at low-temperature,on temperature control and crack prevention.The re-sults show that the special concrete pouring at low temperature can effectively reduce the overall temperature of the structure and reduce the temperature gradient,and effectively curb the risk of structural cracking.关键词
