摘要： 随着城市建设发展和郊区工业化进程加快，工程建设常常面临高填方的问题。为了研究城市郊区建设过程中存在的高填土边坡沉降变形与稳定性问题，结合工程实例并采用有限元理论分析了填筑过程中边坡水平和竖向位移的变化规律。利用强度折减法确定了高填土边坡体内部最可能的滑动面、破坏时产生最大位移位置及稳定性系数。提出了反压护道、强夯法、锚杆格构梁及土工格栅失稳防范对策，对于高填土边坡的设计与施工具有重要的指导意义。

Abstract: High fill embankment is currently more frequently encountered in during the construction with the rapid development of urbanizations. The stability and settlement aspects of the high fill embankments are numerically analyzed by using the finite element method. The potential slip surface, maximum deformation when approaching the failure and the factor of safety are determined by the strength reduction method. Stability mitigation measures include stability berm in front of the embankment, dynamic compaction, ground anchor with grid beams and geogrid methods.
