摘要: 為了研究山區高速公路深路塹邊坡的穩定性問題,基于三維非線性應力及位移有限元計算,對邊坡穩定性進行了數值分析,并與Sarma法的計算結果進行了對比.結果表明,有限元法解決邊坡問題可以起到其他方法不可替代的重要作用.Abstract: Based on calculations of nonlinear stress-deformation by the 3-directional finite element method, this paper numerically analyzed the stability of a mountainous freeway deep cutting slope. The safety factors obtained by this method and Sauna's method were compared with engineering practice. The results show that the finite element method is more effective for analyzing the stability of a slope than traditional methods.
