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。
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.
