To investigate the instability of rock slopes along joint surfaces in water-impounded abandoned open-pit mines under fluctuating water-level conditions, physical model tests were performed using similar materials containing joints and weak interlayers. The mix proportion of the similar materials was optimized through orthogonal experimental design to ensure that their mechanical and seepage properties corresponded to those of the in-situ rock mass. Multiple types of sensors were embedded in the model to monitor pore water pressure, earth pressure, moisture content, and displacement, enabling systematic observation of the multi-field responses of the slope during water-level fluctuations. Working conditions with different numbers of cycles and varied rates of water-level change were designed to examine the deformation characteristics and failure mechanisms of the slope. The results indicate that certain damage to the slope surface is caused by the scouring effect induced by repeated water-level fluctuations at a constant rate, although internal structural damage is limited. This suggests that overall stability is little influenced by slow, single water-level fluctuations. The rate of water-level change is shown to significantly affect slope behavior, with slope displacement increases positively correlated with the rate of water-level decline. Furthermore, the greater the outward-directed pore water pressure of the slope is, the more significantly it is influenced by the hysteresis effect, and the higher likelihood of slope instability becomes.

为解决蓄水废弃露天矿岩质边坡在水位升降作用下易沿节理面失稳的问题,通过制备含节理及软弱夹层的相似材料,开展边坡物理模型试验。基于正交试验设计优化相似材料配比,确保其力学与渗流特性与原岩相似。在模型内部布设孔隙水压力、土压力、含水率及位移传感器,系统监测水位升降过程中边坡的多场响应。通过设置不同循环次数与水位变化速率工况,研究边坡的变形特征与破坏机制。结果表明:相同速率下多次水位升降引发的冲刷效应对边坡表面产生一定程度的破坏,但内部结构损伤较小,单一的水位缓速升降对整体稳定性影响不大。水位的升降速率对边坡影响较为显著,水位下降速率与坡体位移增速成正相关,指向坡体外侧的孔隙水压力越大,孔隙水压力受滞后效应影响越明显,边坡失稳可能性越高。

为解决蓄水废弃露天矿岩质边坡在水位升降作用下易沿节理面失稳的问题,通过制备含节理及软弱夹层的相似材料,开展边坡物理模型试验。基于正交试验设计优化相似材料配比,确保其力学与渗流特性与原岩相似。在模型内部布设孔隙水压力、土压力、含水率及位移传感器,系统监测水位升降过程中边坡的多场响应。通过设置不同循环次数与水位变化速率工况,研究边坡的变形特征与破坏机制。结果表明:相同速率下多次水位升降引发的冲刷效应对边坡表面产生一定程度的破坏,但内部结构损伤较小,单一的水位缓速升降对整体稳定性影响不大。水位的升降速率对边坡影响较为显著,水位下降速率与坡体位移增速成正相关,指向坡体外侧的孔隙水压力越大,孔隙水压力受滞后效应影响越明显,边坡失稳可能性越高。

To investigate the instability of rock slopes along joint surfaces in water-impounded abandoned open-pit mines under fluctuating water-level conditions, physical model tests were performed using similar materials containing joints and weak interlayers. The mix proportion of the similar materials was optimized through orthogonal experimental design to ensure that their mechanical and seepage properties corresponded to those of the in-situ rock mass. Multiple types of sensors were embedded in the model to monitor pore water pressure, earth pressure, moisture content, and displacement, enabling systematic observation of the multi-field responses of the slope during water-level fluctuations. Working conditions with different numbers of cycles and varied rates of water-level change were designed to examine the deformation characteristics and failure mechanisms of the slope. The results indicate that certain damage to the slope surface is caused by the scouring effect induced by repeated water-level fluctuations at a constant rate, although internal structural damage is limited. This suggests that overall stability is little influenced by slow, single water-level fluctuations. The rate of water-level change is shown to significantly affect slope behavior, with slope displacement increases positively correlated with the rate of water-level decline. Furthermore, the greater the outward-directed pore water pressure of the slope is, the more significantly it is influenced by the hysteresis effect, and the higher likelihood of slope instability becomes.
