摘要
采用基于ABAQUS的强度折减有限元法对边坡稳定性进行分析,将折减系数以场变量的形式赋给ABAQUS,利用ABAQUS的后处理功能,将折减系数FV1和边坡坡顶水平位移U1输出到结果中,并绘制出FV1随U1变化的关系曲线,以位移突变为失稳判据,获得边坡的安全系数。在此基础上,通过改变桩的位置,分析桩位于不同位置情况下对边坡的加固效果。结果表明:坡中布桩时安全系数最大,边坡的破坏模式为整体破坏,桩的挡土作用得到充分发挥。
The stability of slope is analyzed through strength decreasing method based on ABAQUS.The reduction factor plays a part in ABAQUS in the form of field variables taking full advantage of the post-processing function of ABAQUS.The relation curve of reduction factor FV1 and the horizontal displacement of a note in the top of slope U 1 has been drawn which are contained in output result.It is believed that the slope is in critical state when the U1 changes suddenly and the security index is the corresponding reduction factor.On the basis of slope stability analysis,the influence of pile location on reinforcement effect has also been studied.It is founded that the optimal pile location is the middle of slope surface.When the pile is inserted in the middle of slope surface,the pile prevents the soil sliding down effectively.
