Abstract: After failure of a gravity retaining wall, a moving landslide was stopped and stabilized by a tie-back retaining wall. The design considered the active landslide and residual strength at the contact between the sliding mass and the rock underneath. Instrumentation installed on anchors showed that only the Coulomb-type active pressure has been mobilized in a period of 5 months since the completion of the structure.
