Research on Fatalness Regionalization of High Slopes at Mountainous Town

Wen Haijia1,2,Zhao Liang2,Huang Qin2(1.Logistical Engineering University,Chongqing 400041,China;2.Faculty of Civil Engineering, Chongqing University,Chongqing 400045,China;)  
In this paper,the geotechnical engineering risk caused by high slopes in mountainous town is studied.The universal evaluation index system was established for the mountain town with the danger of high slope based on analysis of disaster mechanism of high slope.At the same time,the weight of disasters factor in hazard analysis is determined by the analytic hierarchy method in combination with experts grade level;the corresponding mathematical models are made for evaluation of danger regionalization of high slope in accordance with the GIS layer superposition principle to make an approach to the regionalization of the high slopes with catastrophic risk in mountain towns.Practice shows that this approach can give a rather ideal result
