Abstract: This paper presents a case history of evaluating a distressed reinforced soil slope and its possible failure modes. The field investigation, insitu and laboratory tests were performed to characterize the subsurface conditions and geotechnical properties of various soil strata. A two dimensional numerical slope stability analytical model under the seepage conditions was established by using Geostudio software. The stability analyses were performed under both normal operation conditions and extreme conditions. The various failure modes are summarized in the paper based on the analytical results.\=
