介绍了EPS的工程特性,并将其应用到高速公路软土地基拓宽工程中,采用有限元程序进行分析,得出EPS轻质路堤对减轻路堤荷载,增大道路的稳定系数、减小路基沉降具有明显作用,对于沉降难以控制的软土地基等尤其适用,结合工程实例分析得出相关规律。
The engineering characteristics of EPS are introduced and applied to the widening project of soft soil foundation of expressway. The finite element method is used to analyze the EPS embankment to reduce the embankment load, increase the stability coefficient of the road and reduce the settlement of roadbed It has obvious effect and is especially suitable for the soft ground which is hard to be controlled by settlement. Relevant laws are obtained by combining with engineering examples.
