摘要
根据灰色系统理论 ,在全面分析高填方路堤沉降量与时间关系的基础上 ,建立了 2种灰色预测模型 ,即GM(1 ,1 )模型和灰色Verhulst模型 ,并分别对某高填方路基沉降进行了实例预测 ,在此基础上对 2种模型的适用性进行了实例对比分析 ,表明Verhulst模型更适合于预测路堤沉降。
According to the grey system theory, two gery forecast models─GM (1,1) model and Verhust model─were established based on a comprehensive analysis of the relation between the settlement and time of high fill embankment, and were used for settlement forecast of a high fill subgrade. Then a comparison of the two models was carried out. The results show that for settlement forecast of embankment the Verhulst model is more suitable than the GM (1,1) model.
