摘　　要：考虑到在路基填筑过程中,其自身固结引起的地基沉降和位移,如果不对其及时处理,将会影响到施工结束后的沉降和位移,而造成在运营期间不必要的返修。所以在有限元对路基填筑可能引起的沉降和位移进行预测后,进行提前处理。首先通过实际的地质资料及进行相关的实验研究有限元数值分析所需要的参数,再通过有限元分析法预测在填筑路基的过程中路基及地基可能产生的沉降及位移。In the process of subgrade filling,its consolidation would cause the settlement and displacement of foundation.If not eliminated in time,the phenomena will lead the subgrade to settlement and displacement after complition of construction,having the unnecessary repair.Thus,predicting the settlement and displacement potential in subgrade filling by finite element method,the paper conducts treatment ahead of time.First,there is fixing the parameters required for finite value analysis by way of geology data and relative experiments,then predicting the settlement and the displacement of subgrade,potential in filling of subgrade,by finite element analysis,guiding like this the construction going.
