| 摘 要： | 根据公路路基沉降规律和GM(1,1)模型单调指数变化的特性,提出了对原始数列进行分析,合理选择GM(1,1)模型或灰色Verhulst模型。若原始数列处于快速沉降阶段,宜选用GM(1,1)模型;若原始数列处于沉降饱和阶段,宜选用灰色Verhulst模型,并用数学方法证明了灰色Verhulst模型的合理性。

| Abstract: | Based on the rule of roadbed settlement and the characteristic of monotone exponential variety of GM(1,1),the original array is analyzed and reasonable GM(1,1) or Grey Verhulst model is selected in this paper.If the original array is in the stage of rapid settlement,GM(1,1) is more appropriate than Grey Verhulst Model;if the original array is in the tendency of saturation,the latter is better and its rationality of applying in the roadbed settlement is proved by the method of mathematics. |
