摘要
路基的沉降与稳定性控制是高等级公路使用寿命的关键,准确计算路基沉降变形值具有实际应用意义。文中采用灰色GM(1,1)模型及计算原理,进行某一级公路软土路基沉降预测,计算得出软土路基的变形曲线。其模型精度评定指标表明,该方法拟合误差小,预测精度高。
Roadbed settlement and stability control is the key to the service life of the grade highway,and the issue of the soft soil foundation settlement has practical application significance.In this paper,Grey System GM(1,1)model and its principle is used to predict the first class highway soft soil foundation settlement and calculate the deformation curve of the soft soil roadbed.According to the calculated model precision evaluation index,it shows that this method has small fitting error and high prediction accuracy.
