为揭示边坡变形规律,保证边坡安全,采用数学模型对变形监测资料加以分析。边坡变形的时效性明显,为提高灰色模型对边坡不同变形规律的适应性,提高模型的拟合精度和预测能力,对常规的灰色模型进行改进,将常规灰色模型中的常量参数改变为随时间变化的动态参数,由此建立时变参数灰色模型。实例分析结果表明,时变参数模型具有更好的拟合和预测效果,且适应不同变形规律的能力更强。
In order to reveal the law of slope deformation and ensure the safety of slope, mathematical model was used to analyze deformation monitoring data. The timeliness of slope deformation is obvious. In order to improve the adaptability of gray model to different deformation of slope and improve the fitting accuracy and prediction ability of the model, the conventional gray model is improved, and the constant parameters in conventional gray model are changed to Time-varying dynamic parameters, thereby establishing a time-varying parameter gray model. The results of the example analysis show that the time-varying parameter model has a better fitting and predicting effect, and the ability to adapt to different deformation laws is stronger.
