Abstract
Cuifeng town is located in the southwest of Zhouzhi county,Xi'an city.It is a typical loess hilly area with complex and diverse terrain,crisscrossing gullies,and poor geological environmental conditions.Under the erosion effect of rainy season rainfall and the influence of human engineering activities,geological disasters occur frequently,especially in the loess hilly area composed of loess beams and hills,where geological disasters are more developed.Based on the field investigation,supplemented by exploration and experimental data,this paper conduct a systematic and in-depth study on the development laws of geological hazards in the research area.By investigating the geological environmental conditions and historical disasters,new geological hazards were identified;According to the development characteristics and distribution patterns of geological hazards in Cuifeng town,a total of 6 landslides were found to be shallow soil landslides,and one collapse was falling loess collapse induced by slope cutting;Through analysis on the formation conditions and influencing factors of geological hazards,they are mainly related to terrain and landforms,engineering geological rock formations,slope results,hydrological condition,and human engineering activities.Based on these survey results,the geological hazard survey database was updated in a timely manner,and the informatization of geological hazard risk survey data was completed,which provides a basic basis and technical support for disaster prevention and mitigation,land and space planning and use control in Cuifeng town.关键词
