目前高填方边坡在工程应用中较多，高填方边坡稳定和变形对地震作用较为敏感，但对动力作用下边坡的变形、破坏形态、动力响应、震后造成的灾害程度研究不多。通过动力稳定分析，在3种峰值地震加速作用下，当模型都达到了震后平衡时，7度地震作用下边坡的位移和沉降都很小，边坡基本不影响使用，8度地震作用下边坡会局部破坏，9度地震作用下边坡极有可能整体垮塌。通过对比可知，边坡约束越强破坏越严重；地震反应放大系数随着地震动峰值加速度的增大而降低，刚度突变的位置震害最严重。文中运用快速拉格朗日差分法，从边坡变形、破坏形态、动力响应、震后造成的灾害程度对高填方边坡做了研究，对同类高速铁路、高速公路等填方高边坡工程防震减灾具有较大参考意义。

High fill slope has been much adopted in engineering currently,the stability and deformation of high fill slope are more sensitive to earthquakes,yet researches on slope deformation,failure modes,dynamic response and the extent of the disaster after the earthquake due to dynamic action are few.Though dynamic stability analysis,in the three peak earthquake acceleration and the model reaches at equilibrium,displacement and settlement of the slope at earthquake of 7 degrees is very small,basically no affect the use of the slope,the slope will be partially destroyed at 8 degree of seismic intensity,and it is very likely to collapse at 9 degree of seismic intensity;By comparing,the stronger the slope constraint is,the more serious the destruction will be;the amplification coefficient of seismic response is lower as the seismic peak acceleration is increasing,and the stiffness mutation position shall be the most serious damaged.This paper,using the fast Lagrange analysis method,studies the high fill slope from the aspects of slope deformation,failure modes,dynamic re-sponse,and the disaster degree.It has great reference significance for earthquake prevention and disaster reduction of similar high fill slope engineering of similar high-speed rail and highway.
