摘要
针对露天矿开采破坏了岩体结构,原岩的应力平衡状态被打破,围岩支承能力大大降低,边坡处于不稳定状态,存在发生滑坡、崩塌、沉陷等地质灾害的危险性,利用预应力锚索技术和无线通讯技术和网络技术等理论,通过主动监测岩体内应力的变化情况来获取边坡变形和滑移的相关信息,实现了边坡监测的自动化、智能化。经过海州露天矿边坡监测的现场实践发现,海州露天矿边坡暂时处于稳定状态。该技术能够对边坡稳定性进行实时监测,对边坡滑坡灾害防治的顺利实施具有重要作用。
For open pit mining destroys the rock structure, the original rock stress equilibrium is broken, rock bear- ing capacity is greatly reduced, the slope is in an unstable state, geological disasters take place such as landslide, collapse, subsidence. By using pre-stressed anchor cable technology, wireless communication technology, network technology and other theories in this paper, we can get the slope deformation and slip information through proactive monitoring the stress changes in rocks, which are automatic and intelligent. After Haizhou open-pit slope monitoring field practice,it is proved that the slope is in a steady state now. This technology can perform real-time monitoring of slope stability, which plays an important role in the smooth implementation of landslide disaster prevention.
