摘　　要：高速公路路基沉降量的预测不仅关系着高速公路的施工质量与服务水平,同时对高速公路的行车安全也有重要影响.根据路基沉降量的实测资料,通过多种灰色预测模型对路基沉降量进行了数据规律分析及精度对比,选取了最优的灰色预测模型对路基最终沉降量进行预测.为路基稳定性的评价与路基沉降的控制应对提供了参考.The prediction of highway roadbed settlement amount is not only related to the highway construction quality and level of service, but also has an important impact on highway traffic safety at the same time. According to the measured data of roadbed settlement, a variety of gray prediction model were applied to analysis the data law and compare accuracy, the optimal gray prediction model was selected to predict the roadbed final settlement amount. Providing a reference for the evaluation of the roadbed stability and controlling to roadbed settlement.
