Abstract
As an important belt of the Loess Plateau,Gansu Province has a high incidence of geological disasters,posing a serious threat to the safety of local people's lives and property.Taking Dianga Town,Diebu County in Gannan Prefecture as an example,this paper carried out a series of geological disaster hidden dangers identification and high-precision investigations,deepening the understanding of the formation mechanism and development laws of geological disasters.Research found that the landslides in Dianga Town,Diebu County are mainly divided into loess landslides and residual slope laminated landslides.Collapse is divided into foundation rock collapse and soil collapse.The formation of debris flows is affected by geology,topography and precipitation conditions.Disaster-causing models include landslides,collapses and mudslides.In order to prevent and control geological disasters,engineering and non-engineering measures have been taken,such as building support structures,building drainage facilities,building monitoring networks,and popularizing disaster prevention knowledge.These measures provide basic basis and technical support for the prevention and management of geological disasters in Diebu Town.关键词
