In view of the vertical stone cage revetment structure，considering such factors as backfill compaction，cage height，foundation extension length，sensitivity analysis of stress deformation and slope stability is carried out on stone cage structure.When the backfill compaction is increased，the deformation of stone cage retaining wall is reduced and the slope stability is improved.The lower of the stone cage retaining wall height，the higher of its stability and slope stability.The extension length of foundation is beneficial to the stability of stone cage retaining wall.The extension length of foundation should be proper control in engineering.
