摘要
桩承式加筋路堤是一种应用于软土地区路堤工程的地基处理形式。为了研究路堤填筑及交通荷载对地基中超静孔隙水压力及路堤固结沉降的影响,结合某高速公路路堤地基处理工程实例,利用SIGAMA/W建立了桩承式加筋路堤沉降的流固耦合分析模型,分析在路堤填筑时的静水压力的变化规律,及其对固结沉降的影响,得出了相应的结论。
Pile-supported reinforced embankment is a form of foundation treatment applied to embankment engineering in soft soil area. In order to study effect of the embankment filling and traffic loads on excess pore water pressure in the foundation and consolidation settlement thereof, combining with the case study of foundation treatment for certain highway embankment and using SIGAMA/W, the model for fluid-solid coupling analysis on pile-supported reinforced embankment＇s settlement is established so that the laws of hydrostatic pressure change during embankment filling and its effect on consolidation and settlement are analyzed and the relevant conclusion is deduced.
