Abstract: This paper presents a case history of the evaluation of a landslide at the high soil slope on the lefthand side of Station K154 in the Xiarong Expressway Expansion Project in Longyan of western Fujian. The landslide hazards on the soil slopes were investigated and the mitigation measures were evaluated. These measures included unloading at the crest, anchoring in the middle of the slope, retaining wall reinforcements at the toe of slope and drainage improvements. The sitespecific stability evaluation with numerical analysis was performed and the results were compared with the construction monitoring data. The result of comparison indicate that the mitigation measures were effective.
