摘要
高填路堤具有沉降大,沉降时间长,对地基承载力要求高等特点.有效地降低路堤沉降,消除路堤沉降所带来的危害已成为公路建设科技领域的一个重要课题.结合一工程实际,进行高填路堤施工变形数值模拟分析,对换垫处理、路基压实施工进行分析,预测路基的沉降变形,得出了一些有益的结论.
To compare the commonly roadbed,the high-fill road bank has more and lasting time of the settlement,and requests the foundation to has more bearing capacity.It is important to debase the settlement of the road bank and eliminate the disserve of the road construction.An example of fill road bank is made to show the deformation of the construction and imitated by the finite element method.The replacement of the roadbed and the compaction of the road bank are analyzed and the settlement deformation of the road bank is predicted.Some conclusions are obtained and will be helpful to the construction of road bank.
