Study On Geological Hazards In NingQiang

In recent years, with the rapid economic development and increased human activities, frequent geological disasters in China and a wide range of geological disasters caused direct economic losses of up to 27 billion yuan a year. Geological disasters as a constraint to economic and social development, and environment an important factor. This detailed investigation of geological disasters and the stability analysis of geological disasters become increasingly important.WenChuan earthquake in2008 year,made Shaanxi Province, southwest of great influence, especially in Hanzhong, Baoji City, the earthquake caused severe secondary geological disasters, there has been a lot of disaster, danger, the local people's lives and property, constitute a serious threat. In order to protect lives and property of people in earthquake-stricken areas and disaster recovery and reconstruction work to proceed smoothly, Shaanxi Provincial Department of Geology organizations in earthquake disaster detailed investigation.In this paper, the investigation of geological disasters in the county rather on the basis of detailed investigation, by the type of geological hazards; summarizes the characteristics of geological hazards and the distribution of development; analysis of disaster formation conditions and influencing factors.Through the collation of survey data, statistics shows that:NingQiang County is divided into four types of geological hazards, landslides, avalanches and landslides and ground subsidence. A total of field point 396 geological disasters, including landslides 332,83.8%; collapse of 49,12.4%; debris flow 11,2.7%; ground subsidence 4, accounting for 1.1%.Using Geo-studio software for Landslide simulation and stability were evaluated. The results for the prevention of geological disasters NingQiang, County governance has an important role in guiding.
