| Study area is located in Zixi County, East of Jiangxi Province, which is located at the northern foot of Wuyi Mountains and the eco geological environment, is very fragile and geological disaster is frequently happened in Jiangxi Province. In recent years, with the rapid development of social economy, human engineering activities and geological environment happened frequently, and so were all kinds of environmental geological problems and geological disasters. Frequent geological disasters will be a serious threat to people’s life and property safety, and hinder the sustainable development of economy and construction of Zixi County. Therefore, the study of geological hazard’s prevention and treatment in research area, providing scientific basis for hazard prevention and reduction of the local government, which minimizes and prevents losses caused by geological hazards and has significance to protect the safety of people’s life and property.This thesis focuses on the geological hazards in Zixi County; it has carried out a survey on the geological hazard pots on the basis of extensive and comprehensive data about the fundamental geology and disaster geology. Furthermore, it researches the characteristics of the typical hazard distribution and development induced by rainfall with an analysis and conclusion of the hazard mechanism followed. Then it adopts a combination method of engineering analogy, field evaluation and indoor comprehensive assessment (qualitative and quantitative) to evaluate the stability and liability respectively. According to the evaluating results, the thesis conducts a research relating regionalization and quantization thought from macro aspects and takes a hazard partition based on the degree of hazard-prone and prevention applying mathematical methods. At last, it puts forward rational control measures and suggestions, which are of practical significance to the hazard prevention and reduction in the study area. |
