摘要
文章结合某高速公路顺层岩质高边坡开挖及防护工程实例,运用FLAC^(3D)软件建立顺层岩质高边坡的三维施工模型,模拟顺层高边坡的开挖和防护施工过程,揭示坡体的整体变形发展的过程。通过对锚杆(索)框架梁组合防护后边坡位移图及相关数据进行分析,对边坡的稳定性及防护后效果作出评价,为采用合理的防护结构提供依据。
Combining the excavation and protection engineering example of bedding rock high-slope in an expressway,this article established the three-dimensional construction model of bedding rock high slope with FLAC^（3D） software to simulate the excavation and protection construction process of bevel high slope and to reveal the process of overall deformation development of the slope.Through analyzing the slope displacement map and relevant data of anchor（cable）frame beam combination after the protection,it evaluated the slope stability and post-protection effect,thereby providing the basis for the adoption of reasonable protection structure.
