摘　　要：针对不同地域3种可能的填料进行了有限元分析,总结出填料的C、Φ值对拉筋拉力、拉筋应力、侧向土压力、地基土压力、侧向位移等指标的影响。其中C、Φ值的变化对拉筋的拉力及应力基本没有影响,对侧向位移影响不大;但对路堤下部的侧向土压力有较大影响,粘聚力小的土体侧向土压力较大,而路堤上部的侧向土压力不随填料的变化而变化;地基土压力随填料的C、Φ值有较大变化,粘聚力小的土体地基土压力较大。Based on the finite element analysis for the three filling materials from different areas, the effect of the index of C, Ф the tensile strength of the tensive bar, the stress of tensive bar, lateral earth pressure, subgrade soil pressure and lateral displacement are presented, variation of C, Ф index filling materials will have little influence on the strength and stress of tensive bar hardly, and will have influence on lateral displacement with small impacton lateral earth pressure lower at the part of the embankment as the C of the material is smaller then the lateral earth pressure will get bigger. The greater variation of C of filling material, will have influence on subgrade soil pressure, the smaller the C the greater the subgrade soil pressure.
