摘　　要：边坡变形中，氡（Ｒｎ）在地应力作用下不断向外迁移，并有如下规律：１．滑体内外及其不同部位氡（Ｒｎ）浓度平面分布有明显差异；２．滑体垂直剖面上氡（Ｒｎ）浓度分布集中在滑带附近；３．滑坡临滑前氡（Ｒｎ）浓度剧增。利用上述规律对滑坡预报问题进行了研究探讨。In slope deformation,radon migrates outside continuously out ward under the stress and its movement has the follwing laws:1.The radon density is different in different Placements of landslide mass,2.Radon is concentrated near the slide area of landslide,3.The radon density is greatly increased just before the landslide movement.These laws can be used for forecasting the landslide.
