文章研究了早期力学性能的主要影响因素,对梁济运河特大桥箱梁的同材料同配比的混凝土采取不同龄期、不同温度的实验方案,利用MIDAS/Civil有限元分析软件得出了混凝土强度、弹性模量随时间和温度的变化规律,并通过对大量数据的回归得出强度、弹性模量与成熟度的关系式。
In this paper, the main influencing factors of early mechanical properties were studied. The experiment scheme of different ages and different temperatures for concrete with the same material of beam girders in Liangjiadan Grand River Bridge was studied. By using MIDAS / Civil finite element analysis software, Strength, modulus of elasticity with time and temperature changes, and through the regression of large amounts of data obtained strength, modulus of elasticity and maturity of the relationship.
