近些年来,对露天矿边坡是稳定性监控预报技术进行研究对于防控滑坡地质灾害来说具有十分重大的意义。将监控锚索、滑床以及滑体之间相互作用学原理作为理论的基础和前提,将滑床以及滑体相对运行状态力学的监测原理进行提出,将多个因素监测转变成为单一的滑动力力学量监测,并且明确监控预紧力和滑动力之间的关系。通过实施滑坡地质灾害的物理模型试验的结果我们不难看出,在滑坡地质灾害发生之前,边坡岩体自身的内应力会产生连续性的变化,在滑动力比抗滑力大的时候,边坡的岩体也会产生滑动以及变形,而且对边坡岩体里面内应力变化进行捕捉,根据试验的结果我们能够对滑坡地质灾害远程监控预报系统的研究和开发,进而将摄动力的动态变化远程实时监控进行实现,并且提出四种常用的滑坡地质灾害远程监测预警模型,通过在现场实践中应用露天矿山边坡实施边坡稳态预测警报以及实时监控。本文中,笔者就探讨滑坡地质灾害远程监测预报系统及其工程应用。
In recent years, it is of great significance to prevent and control the landslide geological disaster that the research of the open pit mine slope stability monitoring and forecasting technology is of great significance. The principle of interaction between anchor cable, sliding bed and sliding body is taken as the theoretical basis and premise. The monitoring principle of the sliding bed and the relative running state of the sliding body is put forward. The monitoring of multiple factors is transformed into a single sliding force Mechanics monitoring, and explicit monitoring of preload and sliding force relationship. It is not difficult to find out through the physical model test of landslide geological disasters that before the occurrence of landslide geological disasters, the inherent stress of the rock mass will change continuously. When the sliding force is larger than the anti-skid force, According to the results of the experiment, we can research and develop the remote monitoring and forecast system of landslide geological disasters, and then change the dynamic change of the perturbation force Remote real-time monitoring, and put forward four commonly used remote monitoring and early warning models of landslide geological disasters, through the application of open-pit mine slope in the field practice of slope stability forecasting alarm and real-time monitoring. In this paper, the author discusses the landslide geological disaster remote monitoring and forecasting system and its engineering application.
