| 摘 要： | 通过有限元计算软件ADINA建立边坡二维平面应变模型，分析了岩质边坡稳定性影响因素粘聚力C、内摩擦角φ,岩石重度γ、弹性模量E、岩石抗拉强度σt和边坡高度h等对边坡安全系数的影响。计算结果表明：粘聚力C、岩石重度γ和边坡高度h等对一般岩质边坡稳定性的影响较为敏感；内摩擦角φ较粘聚力C对岩质边坡稳定性的影响不太敏感。对岩质边坡稳定性分析研究有一定的应用价值和参考价值。

| Abstract: | Through establishing the two-dimensional plane strain model of slope by finite element software ADINA, the impact of rock slope stability influence factors such as cohesive force C, inner friction angle φ, rock unit weight y, elasticity modulus E, rock tension strength σt, and slope height h on slope safety factors are analyzed. The calculation results indicate that cohesive force C, rock unit weight y and slope height h have sensitive impact on the stability of normal rock slopes ; and the inner friction angle φ has less sensitive impact on the stability of rock slopes compared to cohesive force C, which is of certain application and reference value to the analysis and study of rock slope stability. |
