Abstract : Construction guidelines and techniques for the use of geotextile encapsulated soil elements to contain soil for underwater placement or for use as structural units are described. Additionally, geotextile products, techniques for construction using geotextiles, and experiences at several field sites are described. Properties and characteristics of geotextiles used for construction during the course of this investigation are discussed and described. Pertinent ASM standard tests for measuring and specifying various geotextile properties and characteristics are identified and discussed. GeoCoPS, a public domain computer code for design and analysis of long geotextile tubes, is described and used to emphasize the danger of rupturing long geotextile tubes if applied internal pressure exceeds the design value. Safety factors for long tube design are discussed in connection with GeoCoPS. Several case histories are summarized with a discussion of lessons learned from experiences surrounding construction activities, including filtration demonstrations at Nippersink Lake, near Fox Lake, IL, underwater contraction dike construction at Red Eye Crossing, near Baton Rouge, LA, and dredged material encapsulation for deep water placement at Marina del Rey, near Los Angeles, CA, and New York Harbor, at New York, NY.
