Analysis of Landslide Formation Mechanism and Instability in Yongren County,Yunnan Province
Taking the landslide of Minzu Primary school in Yongren County,Yunnan Province as an example,the deformation characteristics and formation mechanism of landslide geological hazards in the regional geological environment are identified through field investigation and mountain engineering investigation methods.The results show that H1 landslide is in an understable state under natural conditions.Each calculated profile is in an unstable state under rainstorm condition;All calculated profiles under seismic conditions are in an unstable state,so it can be concluded that landslide disasters are mainly affected by terrain conditions and surface water in the region,so effectively inhibiting the impact of water disasters and improving terrain conditions can improve the prevention and control effect of landslide disasters.
