摘　　要：基于强度折减有限元法,本文研究了边坡的稳定性,并建立概化模型进行了分析,结果表明强度折减有限元法能够较可靠地得出边坡的稳定性安全系数,同时提出通过多种失稳判据相结合的方法可以避免单一判据的局限性,能更客观地反映边坡的安全状态。Based on strength reduction finite element method,this paper studies the stability of the slope,and a generalized model was established for analysis.The results show that the strength reduction finite element method(fem)is reliable,and the stability of the slope safety factor is concluded at the same time.The instability criterion is also put forward through a variety of methods,so that the limitations of a single criterion might be avoided,and might reflect the slope safety status more objectively.
