摘要
针对四川省大渡河大岗山水电站右岸边坡工程,利用有限元ANSYS软件建立右岸岩质边坡的数值模型,基于FLAC3D的强度折减法,分析内摩擦角、黏聚力、弹性模量和干湿密度对边坡稳定性安全系数的影响。结果表明,内摩擦角和黏聚力的变化对边坡安全系数的影响较大,是决定边坡安全的主要因素;岩体浸水后弹性模量和干湿密度的变化对边坡安全影响不大。
For the slope project on the right bank of Dagangshan Hydropower Station of the Dadu River in Sichuan Province, we propose a model using ANSYS softwar and analyze the influence of the friction angle,cohesion,modulus of elastic and density changes on the safety factor of slope stability based on FLAC3D strength reduction analysis. The results show that the changes of angle friction and cohesion have much impact on the slope safety factor and mainly determine the stability of the slope,while the changes of the modu- lus of elasticity of soaked rock and its humidity have little impact on slope safety.
