| 摘 要： | 高速铁路地基的沉降研究一直都是工程界最关心的问题之一。本文结合天津蓟港铁路的地基工程，明确地提出了软土地基处理的一种新方法一换填泡沫轻质土法，并运用大型有限元软件ANSYS对换填泡沫轻质土地基进行了精确的模拟计算，从而得出在不同换填泡沫轻质土高度下的地基沉降位移曲线。并且通过比较，在满足铁路规范的前提下，总结得到最经济合理的换填泡沫轻质土高度，对本工程具有实际的指导意义。

| Abstract: | The research on the sedimentation of the foundation in high - speed railway has been one of the concerned problems in civil engineering . Based on a railway foundation project in Tianjin; this paper puts forward a new method replacing the soft foundation with the lightweight foam soil to deal with the soft foundation. In this paper we also use ANSYS software to simulate and calculate the foun- dation which is replaced by the lightweight foam soil and get the sedimentation curves of the foundation under the different thickness of the lightweight foam soil. Through the comparison, we get the most economic and reasonable thickness which also meets the railway standards and it has practical guiding significance to this project. |
