目前单体滑坡预报已进入系统综合预报和实时跟踪动态预报的阶段,但难以准确地预报滑坡发生时间。本文针对华蓥山滑坡预报实践,引入一种改进切线角及对应的单体滑坡预报模型,开发了基于RIA的WebGIS地质灾害快速预警系统,通过分析位移监测数据,实现相应的模型算法,判定滑坡形变阶段,并将其作为单体滑坡预报依据,成功实现了单体预警功能。
At present, the single-body landslide forecast has entered the stage of system comprehensive forecasting and real-time tracking of dynamic forecasting, but it is difficult to accurately predict the landslide occurrence time. In this paper, aiming at the practice of Huayingshan landslide forecasting, an improved tangent angle and its corresponding single landslide prediction model are introduced. A rapid early warning system based on RIA for WebGIS geological disasters is developed. By analyzing displacement monitoring data and implementing corresponding model algorithms, Deformation stage, and as a single basis for landslide prediction, the success of the single early warning function.
