中文摘要：

以某露天矿排土场为例,采用理论分析、实验研究、数值计算和工程设计相结合的研究方法,探明了该排土场工程地质特征分布,深入探讨了渗流对岩石变形力学系统及水对滑动力学系统稳定性的作用机制,获取了积水入渗和毛细水上升对边坡稳定的具体影响,提出了该露天矿排土场排水、止水控制、坡脚置换和压脚设计等具体措施,确保了排土场边坡安全。

英文摘要：

Taking the open-pit mine dump as an example, adopting the theoretical analysis, experimental study, numerical calculation with engineering design, we identify the engineering geological distribution of the dump , deeply discuss that the action mechanism of seepage on rock deformation mechanics system and water on the stability of sliding mechanics system, and obtain the specific effect of water infiltration and capillary water rising to the slope stability. We also propose the specific measures to ensure the safety of the dump slope, for example the drainage, water-stop control, slope toe replacement and design.
