摘要
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。
Single landslide forecast has been into composite forecasting and dynamic forecasting of realtime tracking stage, but it is difficult to forecast the occurrence time of landslide accurately. For local landslide forecast reality in Mr. Huaying, this article referred to an improved tangential angle and the corresponding single landslide forecast model, established the geological disaster rapid warning system of WebGIS based on RIA, and made it as a basis of single landslide prediction by analyzing the displacement monitoring data and implementing the model algorithm to determine the stage of landslide. The result could offer a reference for the quantitative forecasting decision support of single landslide.
