徽(州)-杭(州)高速公路(安徽段)地质灾害遥感调查与评价

Investigation and evaluation of geological hazards on the Hui-Hang express-way (Anhui Province)

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 ,在高速公路预选线共圈定出大小滑坡和崩塌 2 5 2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。根据本次遥感调查提出 :①大阜南侧滑坡 ;①霞井西北段 ;③荷花形 2 92高地滑坡群的预选线路应作调整 ;④榧树滑坡体上的公路预选线应改线另选新线。同时对雄村、尼姑庵、朱村、竹岭脚等处的滑坡需要进行勘察后 ,再提出有效的防治方案。

Hui\|Hang express\|way is located at Wannan Mountains which has complex landform and geo\|tectonic movements, causing geological hazards happen frequently. Two hundred and fifty\|two landslids and calapses are identified along the design line by means of interpretation of astro\|photoes and the investigation of field. These landslids and calapses are mainly distributed along Xin An Rivers, the concave banks of its offshoots, the slopes where the slopes of River and the ditches of River are inter\|cutting and the condition of critical space is very well, and the cutting\|slope section of Old Hui\|Hang Road. The group of landslides should be moderately adjusted along the design line, which is composed of the landslide of the southern of Da fu, the West\|North of Xiajing, and 292 highland of He Hua Xing. The design line on Fei Shu Tailandslip should be changed into a new line. After the landslip of Xiong cun, Ni guan, Zhu cun , Zhu jiaoling and so on are explored, the effective scheme of prevention and harness will be provided.
