中文摘要：

结合高速公路实际边坡变形监测工作的情况，采用经典灰度模型和分形理论，改进了变维分形模型，对边坡沉降变形进行模拟预测，以得到预测精度更高的预测模型。研究结果表明，在本项目中，改进的变维分形的预测精度最高，灰度模型次之，常维分形预测最差。

英文摘要：

In order to get the higher prediction accuracy of forecasting model,based on the reality of highway slope deformation monitoring work,this research adopts the classical gray model and the fractal theory to improve the variable dimension fractal model and simu-lation proj ections for settlement deformation of slope.The results showed that variable di-mension fractal highest in forecasting accuracy in this proj ect,the gray model secondly,the constant dimension fractal prediction the worst.
