Abstract:

On the basis of previous research and development of a remote real-time monitoring system, a case study of the open-pit mine slope in Ping Village was carried out, and  field tests on  landslide monitoring and forecasting were implemented. Under the conditions of working on the open-pit mine slope, remote real-time monitoring was put forth for the whole landslide process. The day of the landslide was  Months 14, 2007. According to the precious data of large-scale field test, comparative analysis was conducted to the sliding destruction characteristics, displacement and monitoring curve of the slope, which indicated that the slope increase of the monitoring curve could forecast the decrease of the stable coefficient, moreover, a sudden increase point of the monitoring curve was the feature point ofprediction. The tests showed that these methods were  scientific and effective for landslide hazard monitoring and forecasting. Comparedwith the traditional horizontal displacement monitoring method, these methods could also achieve remote wireless monitoring, and could significantly advance the forecasting time of a landslide.
