摘　　要：采用动力有限元分析法,输入不同类型的地震波,在不同路堤高度、不同坡比及不同地震烈度情况下,计算分析高填土路堤边坡内孔隙水压力的变化,得出了在地震荷载作用下边坡内孔隙水压力的变化规律,为实际工程设计提供了一定的理论分析依据。With dynamic finite element method, this paper calculates and analyzes the changes of pore water pressure inside the slope of high fill embankment under different types of earthquake wave of different embankment height, different slope ratio and different earthquake intensity, and obtains the rule of pore water pressure changes inside the slope under the effect of earthquake load, which provides certain theoretical analysis foundation for practical engineering design.

关 键 词：高路堤边坡 地震作用 动力有限元 孔隙水压力
