Characteristics and formation mechanism of landslide geological disasters in Longchuan area of northeast Guangdong Province
摘要
Abstract
Longchuan County is located in the hilly area of northern Guangdong Province.Geological disasters occur frequently in the study area,which poses a serious threat to people's lives and property safety,and the situation of geological disaster risk management and control is becoming increasingly severe.On the basis of collecting existing data and field investigation and verification,combined with the results of the fine investigation and evaluation project of geological disasters in Longchuan County(24 towns),this paper analyzes the characteristics of landslide geological disasters and summarizes their formation mechanism based on the comprehensive integration method.Landslides in Longchuan county are mainly small shallow landslides,and the thickness of sliding body is generally in the range of 0～3 m,mainly traction landslides;The temporal and spatial distribution has typical characteristics of simultaneous rain disasters,which is concentrated in the high hills with strong human engineering activities and the foothills of low hills.The typical landslide types in this area are intra-layer sliding landslide and interface sliding landslide.关键词
