摘　　要：在软土地基上修建高等级公路,若按现行方法对路堤分阶段填筑过程中的稳定性进行评价,不能很好地反映施工现场的实际情况。在路堤的分级加载填筑阶段,分析分期填筑周期内孔隙水压力、安全系数等的变化规律,有助于确定施工过程中的最不利情况。During the construction of high grade highway on soft soil foundation, adopting existing method to evaluate the stability in the process of staged embankment construction can not reflect the practical condition of construction field perfectly. In the phase of staged loading and construction, the change rule of pore water pressure and assurance factor during construction periods is analyzed, so that the most disadvantageous condition in construction process can be confirmed.
