摘　　要：为了分析评价遮阳网对冻土边坡的实际降温作用,建立了冻土边坡数值计算模型,将太阳辐射作用等效为气温增量,探讨了太阳辐射对冻土边坡的地温影响,计算了不同遮阳率下的边坡融深,并结合现场监测,得到了遮阳网的实际遮阳率以及对冻土上限的提升效果。In order to analyze the actual cooling effect on the permafrost slope by solar-shading screen, slope numerical calculation model is set up, with the solar radiation effect equal to the temperature increment, to figure out how solar radiation impacts the temperature of permafrost slope. Combined with monitoring data, melt depth of slope is calculated with different shading rate to get the actual shading rate of solar-shading screen and the effect to lift the permafrost table.
