摘　　要：在实地踏勘的基础上,对云南泸水县国门小学滑坡的地质地貌条件以及滑坡体的基本特征进行了详细的分析。在此基础上,运用极限平衡理论对该滑坡的公路段以及整个滑坡体,分3种工况进行了稳定性研究。结果表明:在较为干燥的条件下,各段滑坡体均处于稳定状态,但在强降雨或是地震工况下,则表现为基本稳定-欠稳定状态。为了防止地质灾害发生,结合相关理论提出了治理方案,建议实施支挡和排水工程。On the basis of field reconnaissance,this article analysis the geological and topo-graphical conditions and basic characteristics of Guo Men elementary school landslide in Yunnan Lushui County.On this basis,the limit equilibrium theory is used to analysis the stability of the road section and the landslide in three conditions.The results show that each section of the landslide is in stable state in the condition of dry,but basically stable or unsta-ble state in the condition of heavy rainfall and earthquake.According to relevant theory,sup-port and drainage works should be taken to prevent the occurrence of geologicaldisasters.
