摘要
本文在试验基础上对大塅溢流坝段混凝土的徐变、弹性模数、瞬时弹性变形,松驰系数、线膨胀系数进行了研究和探讨,并给出了弹性模数、徐变度及松驰系数计算公式,其试验研究成果可供溢流坝段进行应力分析之用。
Based on tests, this paper studies and discusses creep deformation, elastic modulus, instantaneous elastic deformation, coefficient of relaxation, coefficient of linear expansion of concrete for overflow dam of Daduan hydroelectric power station and the calculation equations for elastic modulus, creep rate and coefficient of relaxation have been given. The test result can be used in stress analysis for overflow dam.
