| 摘 要： | 运用灰色理论对高速公路软土地基沉降进行预测,建立不等时距的预测模型GM(1,1),采用后验差法对模型的可靠性进行检验,弥补等时距GM(1,1)模型的不足。同时,结合沿江高速公路常州段实测数据,进行计算机模拟,得出了预测模型,并与实测结果进行对比和分析,结果理想可靠,证明了该法的实用性。

| Abstract: | The grey theory is used to predict the soft clay ground settlement of expressway in the paper, an unequal time-interval forecasting model of GM(1,1) is established, the precision of the model is tested and verified by the posterior variance examination, it makes up for the equal time-interval model of GM(1,1). Based on the site settlement information of the expressway of Yan Jiang Chang Zhou, the forecasting model simulation results are analyzed and compared with the practical settlement with good resuts proved to be practical. |
