摘要
基于加锚节理岩体等效力学模型,应用三维弹粘塑性有限元法模拟了溪洛渡拱肩槽岩石高边坡的开挖过程和锚固措施,分析比较开挖不锚固与开挖锚固两种方案下边坡岩体的位移、应力和点安全系数等分布规律。结果表明两种方案下边坡稳定性均较好。
The cutting process and anchoring measures for the high slope of the abutment trough of Xiluodu arch dam are simulated by 3-D E-V-P FEM on the basis of equivalent mechnical model of jointed rock mass reinforced by anchor bars; the distribution pattern of stress, displacement and safety factor of the rock slope are analyzed by the comparison of two alternative schemes, the rock slope with anchoring or without anchoring; the result shows that the slope stability of both schemes is well up to the standard.
