“醉汉林”作为滑坡和边坡变形特征标志的意义——以陕西陇县地区为例
-
摘要: “醉汉林”一般被当做滑坡存在的一种标志。在陕西宝鸡地区进行地质灾害详细调查的过程中,发现变形边坡也有“醉汉林”分布。对陕西陇县郭家庄变形边坡“醉汉林”的树木倾斜角与边坡的倾角进行了测量,并结合几何学分析,认为树木倾斜角反映了边坡倾角的变化,并得出边坡倾角不断变陡是该地区边坡变形的一种主要方式的结论。研究结果表明,“醉汉林”有着多样而具体的指示意义：“醉汉林”记录了边坡变形的历史,可以作为区分滑坡与变形边坡的标志,“醉汉林”可以指示滑坡及边坡的状态,还可以判断滑坡剪出口是否存在。Abstract: The "drunk men wood" is usually considered as an indication of a landslide.During a detailed investigation of geological hazards in Baoji,Shaanxi,the authors found "drunk men woods" on deformed slopes.Through measurements of leaning angles of trees of a "drunk men woods" at the Guojiazhuang deformed slope in Longxian County and slope angles,combined with a geometric analysis,the authors think that the leaning angles of trees reflect the variation of slope angles,and thus they draw the conclusion that continuous steepening of the slope angle is a main way of slope deformation in the area.Study shows that "drunk men woods" has diverse and concrete indicative significance:it records the history of slope deformation and may serve as an indication distinguishing a landslide from a deformed slope,and additionally it may indicate the states of the landslide and slope and may also be used to judge where there exist landslide shear cracks.
