【摘要】 滑坡预测在线状工程的防灾减灾中起着关键作用。为了实现斜坡稳定性的可视化区划与预测,在地理信息系统GIS平台和数字高程模型DEM的基础上,利用水文-力学耦合模型,以位于泾川县的某段输气管线为研究区,研究降雨条件下斜坡变形失稳的定量预测问题。并将预测结果与实际滑坡点进行对比分析,验证模型评价结果具有较高的精度。更多还原

【Abstract】 Landslide hazards prediction plays a key role in preventing disasters and reducing damages of striated engineering. A hydrologymechanical coupling model in landslide hazards prediction model is used in the study area, which is a gas transmission line located in Jingchuan. Based on geographic information system(GIS) and digital elevation model(DEM), the model has considered the quantitative forecast of how the slope has deformed under different rainfall conditions. Then, the aim to make a visual regionalism and prediction of the stability of the slope body will be achieved. It approves the high accuracy of this model in regional landslide hazard prediction through a comparison between the predicted results with the actual landslide bodies.更多还原
