高寒高烈度山区公路溜砂坡地质灾害监测预警研究

Research on Monitoring and Warning of Geological Hazards of the Sand-sliding Slope in High-Cold and High-Intensity Mountainous Areas

针对高寒高烈度山区公路溜砂坡地质灾害,采用理论研究与案例分析相结合的方法,得出溜砂坡监测预警预报关键参数,建立监测预报模型,判定了和田山区公路典型路段溜砂坡预警级别。研究得出溜砂坡的预警预报关键参数:挡土墙与坡间的“残余库容体积”、“挡土墙高度”、“年平均产屑率”,溜砂坡监测预报模型判定了和田山区公路5处典型溜砂坡路段的预警级别。

Aiming at the geological hazards of highway sand slope in high-cold and high-intensity mountainous areas,the key parameters of monitoring,warning and forecasting of sand slope were obtained by combining theoretical research with case analysis,and the monitoring and forecasting model was established to determine the warning level of sand slope in typical highway sections in Hotan mountainous area.The key parameters of early warning and prediction of sandy slope are studied:"residual storage volume","retaining wall height"and"annual average debris yield rate"between the retaining wall and slope.The monitoring and prediction model of sandy slope determined the warning levels of 5 typical sandy slope sections of highways in Hotan Mountain area.
