灰色系统模型在混凝土坝应力分析中的应用

The Application of Gray System Model in Stress Analysis of Concrete Dam

在混凝土坝蓄水初期应力观测数据较少的情况下,为分析坝体的应力影响因素和变化规律,该文利用有限元确定性模型与灰色系统模型相结合的方法,建立了混凝土坝应力分析灰色混合模型。桃林口水库混凝土坝体的应力分析结果表明该方法是合理的。

To analyse the impact factors on stress of concrete dam and stress changes, especially in the case of insufficient observations at the beginning of storing water, Gray Mix Model are developed in this paper by integrating the determinable finite element model and gray system model. The model has been applied to stress analysis of Taolinkou concrete dam, the results show that the model is applicable.
