Landslide hazard from gelifluction in Qinghai-Tibet plateau and stability analysis method

  • 摘要: 青藏高原多年冻土地区融冻泥流型滑坡属于长度与深度之比为无限大的浅层滑坡,应用无限斜坡分析方法研究滑坡的稳定性是完全合适的。考虑渗流方向与斜坡方向一致的情况,应用有效应力原理,本文推导出不同含水条件下融冻泥流型滑坡安全系数的解析表达式,绘制出了干土坡和完全饱水土坡稳定性分析图表,并对青藏公路K30 35里程融冻泥流型滑坡进行了稳定性分析及评价。
    Abstract: Landslide in gelifluction is a new geological hazard caused by human activity in permafrost region of Qinghai-Tibet plateau. It belongs to shallow landslide with small length-width ratio. In general, infinite slope analysis method is applied to it. According to identical seepage direction to slope surface,with the effective stress principle,the analytical expression of safety factor of the landslide in gelifluction with different water content conditions is derivated and stability analysis chart of dry and fully saturated water soil are plotted. Lastly,taking the Landslide in gelifluction in milestone K3035 of Qinghai-Tibet highway as an example,the paper analyzes and evaluats the stability of the landslide.
