摘 要: | 弹性模量是混凝土的重要力学性能指标.为研究酸雨环境下混凝土的弹性模量劣化规律,应用灰色理论新陈代谢GM(1,1)模型,建立了受酸雨腐蚀混凝土静力抗压弹性模量预测模型,并对文献中模拟3种酸度的酸雨环境的试验数据进行了验证,理论模型的计算结果与试验数据吻合较好.研究表明,新陈代谢GM(1,1)模型简便易行,能够有效地预测受酸雨腐蚀混凝土的弹性模量.

Abstract: | Elastic modulus is an important mechanical parameter of concrete. To investigate the elastic modulus of concrete under acid rain environment, Grey theory metabolic GM(1, 1) model was applied in this paper. A Grey model GM(1, 1) was established to predict the elastic modulus of concrete corroded under acid rain, and the model is investigated through its ability to reproduce available experimental trends. The analytical results of the oretical model was in accordance with the experimental data. It is shown that metabolic GM(1, 1) model put forward in this research is a feasible and reliable model for the prediction of the elastic modulus of the concrete corroded under acid rain. |
