摘　　要：基于地质勘查资料与监测数据,分析了柏堡滑坡的变形特征,研究了滑坡变形失稳机理;利用Geo-Studio进行了不同工况下的滑坡稳定性分析及预测。结果表明:地形地貌、地层岩性是柏堡滑坡变形的主控因素,大气降雨是滑坡变形的直接诱发因素,在内外因素的综合影响下,促使滑坡变形失稳;滑坡变形与持续性降雨和强降雨关系十分紧密,其中持续性降雨对柏堡滑坡变形影响更大,若出现持续性降雨,滑坡存在发生整体变形的可能性。Based on the geological exploration data and monitoring data,the deformation characteristics of Baibao landslide are analyzed,and the deformation and instability mechanism of the landslide is studied;The stability analysis and prediction of landslide under different working conditions are carried out by using Geo-Studio.The results show that the landform and formation lithology are the main controlling factors of Baibao landslide deformation,and the atmospheric rainfall is the direct inducing factor of landslide deformation.Under the comprehensive influence of internal and external factors,the landslide deformation and instability are caused;Landslide deformation is closely related to continuous rainfall and heavy rainfall.Among them,continuous rainfall has a greater impact on the deformation of Baibao landslide.In case of continuous rainfall,the landslide has the possibility of overall deformation.
