十堰500kV变电站滑坡变形特征与稳定性研究

十堰500kV变电站站场西南侧地表出现贯穿性裂隙,滑坡迹象明显.以翔实地质勘察资料为依据,将地质调查与深部位移监测成果结合起来,系统分析了该滑坡的变形影响因素、变形现状与发展趋势,预测了滑坡变形失稳模式;将宏观分析与变形监测成果结合起来,对滑坡的稳定性作出了比较客观准确的评价,为应急抢险及综合治理提供了重要依据.

Characteristics and stability study on landslide deformation of a 5ookV transformer substation in Shiyan

On the ground surface southwest of the 500 kV transformer substation in Shiyan,it appears penetrating fissure and the obvious landslide signs.On the basis of the accurate data of geological prospecting,and in combination with geological investigation and deep displacement monitoring results,the factors affecting the deformation,present deformation situation and the development tendency of the landslide are systematically analyzed,and the landslide deformation instability mode is also forecasted.With combination of macro analysis and deformation monitoring results,a more objective and accurate evaluation on stability of landslide is made and thus a sound basis of emergency rescue and comprehensive management is provided.
