摘　　要：徽-杭高速公路(安徽段)位于皖南山区腹地、地形地貌复杂,构造发育,是地质灾害多发地区。利用航卫片解译结合野外调查,在预选线共圈定出大小滑坡和崩塌252处,这些滑坡与崩塌多分布在新安江及其支流凹岸一侧或河流岸坡与沟谷切割且临空条件较好的斜坡地带,以及徽-杭老公路切坡地段。分布在预选线的大阜南侧滑坡、霞井西北段,荷花形292高地滑坡群的线路应作调整;榧树土太滑坡体上的线路应改线另选新线。对雄村、尼姑庵、朱村、老竹岭脚等处的滑坡需进行勘察后,再提出有效的防治方案。The Huizhou-Hangzhou expressway(Anhui section) lies in the hinterland of south Anhui mountainous region with complex landforms and developed structures,where geological hazards take place frequently Airborne and satellite image interpretation combined with field investigation discloses 252 places of landslides and collapses of varying scales,which mostly distribute along concave banks of the Xin`anjiang River and its branches,or in the zones of hanging state where river bank slopes crosscut grooves,and in slope cutting segments of the preliminarily chosen expressway route The route should be adjusted at the landslide south of Dafu, northwest segment of Xiajing, and the lotus formed landslide cluster of No 292 Highland A new route part will be chosen in stead of that on the Feishutai landslide body Effective countermeasures are required after a survey is conducted at the places such as Xiongcun, Nigu`an, Zhucun, Laozhulingjiao etc
