| 摘 要： | 以灰色系统理论为基础,将高路堤沉降过程看成一个灰色系统,建立适合高路堤沉降预测的GM(1,1)沉降预估模型及其残差模型,将某高速公路的已知观测数据代入GM(1,1)模型,推算该观测点的最终沉降。同时,在室内进行土工离心模型试验,将试验结果与灰色模型得到的预测结果进行对比分析,表明预测精度良好。

| Abstract: | Based on gray system theory, regarding the subsiding process of high embankment as a gray sys- tem, a GM（1,1 ） settlement forecast model adapting to the settlement forecast of high embankment and its residual error model are established. Through inputting the known data from observation of an expressway into GM （ 1,1 ）, the final settlement of the observation point is calculated. Meanwhile the indoor geotechnical centrifuge model test is carried on. The comparison between test result and forecasted result based on Gray Model indicates that the precision of forecast is Deflect. |
