| 摘 要： | 以彭湖高速公路K41+200段软土路堤填筑为研究对象,根据plaxis强度折减法与地下水渗流原理建立了分层填筑并考虑地下水渗流的有限元模型,进而分析了不同填土施工速度、填方高度、渗流与非渗流条件下软土路基的稳定性,得到了软土路基施工合理的分层厚度、分层间隔等参数,对于软土路基安全施工具有一定的指导意义.

| Abstract: | On the basis of plaxis strengthen reduction theory and principle of groundwater infiltration,embankment of K41+200 along Peng-hu expressway was taken as the object to establish the FEM model of layer filling and groundwater seepage flow.Then,the stability of soft soil embankment in various filling construction speed,different height of embankment and in the condition of infiltration or not were analysed.Finally,the influence parameters of filling construction,such as thickness of filling layer and interval ... |
