摘　　要：本文通过现场调查,分析了湖南省安化县渠江镇大塘村滑坡的基本特征和形成机制,并对其稳定性进行了分析和评价。结果表明:大塘村滑坡在天然工况下处于稳定状态,在暴雨工况下,由于结构面软化、岩石饱水密度增大等因素导致坡体稳定性降低,处于不稳定状态。提出了防治对策,认为“截排水+布设抗滑桩+布设挡土墙”的工程治理方案适合应用于大塘村滑坡治理。Based on field investigation,the paper analyzed the basic characteristics and formation mechanism of landslide in Datang Village,Qujiang Town,Anhua County,Hunan Province,and evaluated its stability.The results showed that the landslide is in stable state under natural conditions,and the stability of the slope reduced and was in an unstable state under heavy rain conditions,due to the softening of structural plane and the increase of saturated density of rock.The prevention countermeasures were put forward that the engineering treatment scheme of"drainage interception+building anti-slide pile+building retaining wall"was suitable for landslide control in Datang Village.
