摘　　要：高速铁路CFG桩复合地基(路基)沉降是一个复杂的过程,采用MATLAB语言编写了基于XGM(1,1)模型预测地基沉降的程序,并将其应用于CFG复合地基沉降量的预测。通过对灰色预测XGM(1,1)模型在工程实例的应用和对比,证实XGM(1,1)模型运用到工程实际中是可行的。The settlement of CFG pile composite foundation（subgrade） of high-speed railway is a complex process.The program for foundation settlement prediction based on XGM（1,1）model is prepared using MATLAB language and applied in the prediction of CFG pile composite foundation settlement,which received good effect.Through application and comparison of grey prediction XGM（1,1）model in practical engineering,it is proven that XGM（1,1）model is feasible to be applied in the practical engineering.
