【摘要】 根据岩锚支护作用机理, 建立了一种三维损伤岩锚柱单元模型模拟锚杆的支护效果, 将建立的力学模型应用于笔者负责的深圳市迄今规模最大的滑坡地质灾害治理工程项目———深圳市大南山山体滑坡加固治理设计,取得了显著的经济效益。更多还原

【Abstract】 According to interactive mechanism of jointed rockmass and bolt, a cylindrical damage rock-bolt element model is proposed in this paper to simulate reinforcing effect of bolts in jointed rockmass. The model is applied to reinforcing design for Dananshan landslide which is the largest geological hazard so far in Shenzhen. The landslide prevention is designed by first author and remarkable economic benefits is obtained.更多还原
