本文介绍了金川露天矿边坡滑动—倾倒复合变形实例,它是在两种机制共同作用下发生的。岩体条块状碎裂结构对变形机制和发展过程起了控制作用。岩体结构的变形特性基本上符合蠕变三阶段发展规律,变形和时间呈幂函数曲线关系。岩体变形在本质上主要是其断层蠕变和结构面的剪切和开裂。岩体蠕变特性是岩体结构效应和时间效应的综合体现。
This paper presents an example of sliding-dumping composite deformation of the slope of Jinchuan Open-pit Mine, which occurs under the combined effects of the two mechanisms. The massive block structure of rock mass plays a role in controlling the deformation mechanism and development process. The deformation characteristics of the rock mass structure basically conform to the three-phase development law of creep, and the relationship between deformation and time is a power function curve. The deformation of rock mass is essentially the fault creep and the shearing and cracking of the structural plane. The creep properties of rock masses are a comprehensive manifestation of rock mass structure effects and time effects.
