摘要
仓上露天矿于2005年闭坑,后期由于抽水重复利用导致边坡水位升降循环变化。为了研究水位升降对该边坡岩石力学参数的影响,选取2种典型岩石进行饱水-失水循环条件下的单轴压缩试验,得到了2种岩石的力学参数损伤规律,为水岩作用下的边坡工程稳定性分析提供了有益的依据。
Cangshang open pit mine closed pit in 2005, and due to pumping, water reuse lead lift cycle change of slope water level in the late. In order to study the influence of water level fluctuation on rock mechanical parameters of the slope, the uniaxial compression test of two types of rocks with different water saturation-water loss are carried out. The damage evolution law of rock mechanics parameters under water-rock interaction was determined, and might be used in the bank stability analysis.
