Geological Disasters Divisions And Study On Prevention Of Early Warning Countermeasures In The City Of Huaying

China is susceptible to geological disasters, especially in the western provinces of Yunnan, Sichuan, Chongqing and Guizhou. The prevention of geological disasters will not only influence the country’s economic development and people’s lives and property safety, but also the construction of major national projects. There is a broad distribution of geological disasters in Huaying territory due to the presence of Huaying Mountain, an important mountain in eastern Sichuan. And the study on the geological disasters in this city is of great importance to the prevention of geological disasters. With strong internal neotectonic movement, complex geological conditions, developed folds and faults, high mountains and deep valleys, and undulating terrain, Huaying is one of the national geological disaster-prone areas. Major geological disasters include landslides, avalanches, landslides and etc. Various disasters are interconnected with each other, forming a disaster chain through energy and matter movement.Based on "Guang’an Geological Disaster Prevention Plan (2011-2020)", this thesis analyzes the geological disasters in this area. And the author provides a prevention plan and proposes the establishment of Huaying geological disaster management information system according to actual geological conditions of Guang’an and Huaying and the principle of geological disasters divisions. In this thesis, the meteorology, geology, hydrogeology, engineering geology, geological disaster situation of Huaying are studied, and various features of the Huaying geological disasters are analyzed based on the research in the disastrous areas. On the basis of the zoning principles of geological disasters, the thesis divides the disastrous areas into different susceptibility and prevention levels. Moreover, the geological disaster monitoring and early warning system programs and geological disaster prevention countermeasures are also studied to provide scientific support for Huaying geological disasters prevention and treatment.
