【摘要】：针对小样本观测数据边坡变形预测,提出一种基于灰色系统理论和分形几何耦合的分形预测模型。该模型利用灰色系统理论来对原来分形模型中的分形维数进行拟合预测,通过对比传统分形模型和预测耦合模型预测结果的准确性和稳定性。结果表明在现有小样本监测数据序列情况下,改进分形模型不仅在预测精度上比传统分形模型高,而且还具有一定的抗波动性能力,边坡变形预测的稳定性也有所提高。
[Abstract]:For small sample data of slope deformation prediction, proposes a fractal prediction model of grey system theory and fractal geometry coupling based on grey system theory to forecasting the fractal dimension of the original fractal model based on the model, by comparing the traditional fractal model and coupled model for the prediction accuracy and stability. The results show that in the current small sample monitoring data under the condition of not only improved fractal model in prediction accuracy than the traditional fractal model, but also has the ability to resist some volatility, also increased the stability of the slope deformation prediction.
