Geosynthetics for soil reinforcement R.D. Holtz, Department of Civil & Environmental Engineering, University of Washington, Seattle, WA, USA

ABSTRACT: The paper introduces geosynthetic materials and briefly describes their types and manufacture, functions and applications, properties and tests, design, selection, and specifications. Then the three primary soil reinforcement applications using geosynthetics – embankments on very soft foundations, increasing the stability of steep slopes, and reducing the earth pressures behind retaining walls and abutments – are discussed in some detail. Emphasis is on the properties of the geosynthetics required for design and construction.
