The present invention relates to an anchor-supported retaining wall supported by a planar frictional anchor, capable of being more economically and stably constructed by supporting an anchor by friction resistance by coupling a planar friction anchor installed in the piled ground to a wall positioned at a front surface of backfill soil by a tension connector, and a method for constructing the same. The anchor-supported retaining wall supported by a planar frictional anchor comprises : a wall integrally and vertically formed to support bending moment by a soil pressure by being positioned at a front surface of the backfill soil; a plurality of planar friction anchors which are buried in the backfill soil and formed in a heavyweight planar shape with a large surface area to be installed in the backfill soil by friction force between a lower surface and a ground surface of the backfill soil caused by a self-load and the weight of the backfill soil, and allow the wall to support a soil pressure of the backfill soil; and a tension connector which has one end vertically movably hinged and coupled to a rear surface of the wall to be able to vertically and laterally rotate and the other end coupled to the planar friction anchor to transmit the load of the wall to the planar friction anchor.
