GEOTEXTILE REINFORCEMENT FOR A SOIL SLOPE, LAWRENCE BERKELEY LABORATORY, CALIFORNIA, USA

This case history describes a 90m long 24m high reinforced soil slope at the site of the Lawrence Berkeley Laboratory, Berkeley, CA, USA. Two geosynthetic materials were used for the reinforcement: (1) a high density polyethylene (HDPE) SR2 geogrid, designed to provide overall stability; (2) a polypropylene SS2 geogrid, intended to provide near surface stability and minimise bulging at the face. The SR2 had an ultimate strength of approximately 80kN/m, and a recommended allowable strength of 29kN/m. The slope was designed to be constructed with a series of benches and intermediate slopes of 0.75H:1V. Its design considered overall stability, benched slope stability, and near surface stability. The calculated safety factor was about 1.25. Since its completion in 1986, the reinforced slope has performed as intended. For the covering abstract see IRRD 865821.
