某换流站边坡变形机理及应急治理设计

Mitigation of the Excessive Deformation of a Slope for the Electricity Transformation Station

针对西南地区某换流站变形最严重的DE段填方边坡进行了变形特征和变形监测分析,总结了边坡变形原因及破坏模式,并对边坡进行稳定性评价,设计应急治理方案,为以后的工程设计提供参考。

This paper presents a case history of the mitigation of the excessive deformation of a fill slope for the electricity transformation station.The entire fill embankment was monitored for the deformation during the construction.The observation results indicated that the worst deformation was at the Segment No.DE.The factors that attributed to the excessive deformation and the potential failure modes are discussed in the paper.The stability of the fill embankment was evaluated and the emergency mitigation measures are also provided.
