【摘要】 合丰外东山滑坡是皖南山区典型的碎石土滑坡之一。通过现场踏勘及钻孔,查明该滑坡为浅表层堆积体沿基覆接触带产生的蠕滑。结合现场位移监测数据分析斜坡变形情况。采用Geostu-dio2007软件耦合分析持续暴雨条件下斜坡位移和稳定性的变化特征。结合变形情况,评价坡体稳定性,提出稳定位移预测值,为政府部门提供灾害防治的理论依据。更多还原

【Abstract】 The Hefeng Waidongshan landslide is one of the typical gravel-soil landslides in the area.The field investigation and drilling survey found that the landslide is shallow debris creep along the contact zone of the bedrock and mantle.The displacement monitoring data was used to analyze the slope deformation.Geostudio2007 software was used to discuss the slope displacement and stability under the conditions of continuous heavy rain.The slope stability is evaluated and the predictive value of stable displacement is proposed to offer a basis for the local government.更多还原
