摘　　要：文中以云南省永仁县民族小学滑坡为例,通过现场调查以及山地工程等方法,查明了该区域地质环境内滑坡地质灾害的变形特征以及形成机理。研究表明,H1滑坡在自然工况下处于欠稳定状态,暴雨工况各计算剖面处于不稳定状态,地震工况各计算剖面均处于不稳定状态,因此可以得出,滑坡灾害主要受区内地形条件和地表水影响,故有效抑制水害影响和改善地形条件可提高滑坡灾害防治效果。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.
