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.
