摘　　要：该文讨论了灰色系统理论在软土路基沉降量预测中的应用 ,以京珠高速公路灵山试验段沉降观测数据为例 ,建立了沉降量灰色预测模型 ,并与三点法、双曲线法的预测结果以及实测结果进行了对比 ,结果表明 ,灰色预测模型的预测沉降量与实际沉降量更接近。The paper discusses the application of grey system theory to the roadbed settlement prediction of soft soil. Taking the observed settlement data of the Linshan experimental section of Beijing-Zhuhai expressway as an example, the grey prediction model of settlement is established, and compared with the results of three-point method, hyperbola method and the observation results. It shows that the predicted settlement of grey prediction model is very close to the practical settlement. Finally, the problems needing attention are presented for the analysis of the grey model prediction.
