Prehistoric Landslide Stabilization with Ground Anchors and Surface Reaction Pads
Corfu Street is perched on an isolated, lenticular plateau midway up the south valley wall of the Ohio River in the West End neighborhood of the City of Pittsburgh. This plateau represents the head of a prehistoric rockslide that likely occurred following a period of glacial meltwater erosion during the Pleistocene Epoch. The plateau comprises the surface of a 40-foot thick layer of landslide debris (soil and rock) resting on a mildly sloping clay stone rock ledge. A steep, 150-foot high rock slope drops from this plateau to an active mainline railroad track below. Following a year-long period of above-average rainfall, the landslide, involving more than 120,000 cubic yards of accumulated soil and rock debris, was re-activated by an apparent significant rise in the groundwater table and resulting saturation of the slide mass. This paper describes the geotechnical evaluation and monitoring of the landslide and the design and construction of a system of ground anchors and surface reaction pads installed to stabilize the landslide.
