Geosynthetic Reinforced Soil (GRS) Walls


Book Description

The first book to provide a detailed overview of Geosynthetic Reinforced Soil Walls Geosynthetic Reinforced Soil (GRS) Walls deploy horizontal layers of closely spaced tensile inclusion in the fill material to achieve stability of a soil mass. GRS walls are more adaptable to different environmental conditions, more economical, and offer high performance in a wide range of transportation infrastructure applications. This book addresses both GRS and GMSE, with a much stronger emphasis on the former. For completeness, it begins with a review of shear strength of soils and classical earth pressure theories. It then goes on to examine the use of geosynthetics as reinforcement, and followed by the load-deformation behavior of GRS mass as a soil-geosynthetic composite, reinforcing mechanisms of GRS, and GRS walls with different types of facing. Finally, the book finishes by covering design concepts with design examples for different loading and geometric conditions, and the construction of GRS walls, including typical construction procedures and general construction guidelines. The number of GRS walls and abutments built to date is relatively low due to lack of understanding of GRS. While failure rate of GMSE has been estimated to be around 5%, failure of GRS has been found to be practically nil, with studies suggesting many advantages, including a smaller susceptibility to long-term creep and stronger resistance to seismic loads when well-compacted granular fill is employed. Geosynthetic Reinforced Soil (GRS) Walls will serve as an excellent guide or reference for wall projects such as transportation infrastructure—including roadways, bridges, retaining walls, and earth slopes—that are in dire need of repair and replacement in the U.S. and abroad. Covers both GRS and GMSE (MSE with geosynthetics as reinforcement); with much greater emphasis on GRS walls Showcases reinforcing mechanisms, engineering behavior, and design concepts of GRS and includes many step-by-step design examples Features information on typical construction procedures and general construction guidelines Includes hundreds of line drawings and photos Geosynthetic Reinforced Soil (GRS) Walls is an important book for practicing geotechnical engineers and structural engineers, as well as for advanced students of civil, structural, and geotechnical engineering.







Designing with Geosynthetics


Book Description

Geosynthetic materials have entered the mainstream in the professional arena and are no longer considered new construction material. Professionals need to keep up with the nuances of how geosynthetics work. Emphasizes design by function; overviews all types of geosynthetics, with stand-alone units on particular materials. Uses S.I. units for all problems and examples. Expands coverage of containers and tubes in the geotextile chapter. Discusses walls and slope design, including seismic analysis, in the geogrid chapter. Treats wet landfills, agricultural waste, waste stability, and dam waterproofing in the geomembrane chapter. Discusses new products and related performances in the geosynthetic clay liner chapter. Discusses new products and related behavior, including fiber reinforcement and wall drainage, in the geocomposite chapter. Adds a completely new chapter on geofoam. A useful reference for transportation, geotechnical, environmental, and hydraulics professionals and engineers.




Geotextiles and Geomembranes in Civil Engineering


Book Description

This manual describes, in detail, all the uses for geotextiles and geomembranes (synthethic polymers) in civil engineering: erosion control systems, embankments, pollution control systems, water storage, drainage, and road construction. Focuses on the application of geotextiles in bank and bed protection, construction and drainage. Also deals with production technology, properties and testing of geotextiles, and the designing of the geotextile-element in a structure. Aspects of execution and maintenance are also treated.




Assessment of the Performance of Engineered Waste Containment Barriers


Book Description

President Carter's 1980 declaration of a state of emergency at Love Canal, New York, recognized that residents' health had been affected by nearby chemical waste sites. The Resource Conservation and Recovery Act, enacted in 1976, ushered in a new era of waste management disposal designed to protect the public from harm. It required that modern waste containment systems use "engineered" barriers designed to isolate hazardous and toxic wastes and prevent them from seeping into the environment. These containment systems are now employed at thousands of waste sites around the United States, and their effectiveness must be continually monitored. Assessment of the Performance of Engineered Waste Containment Barriers assesses the performance of waste containment barriers to date. Existing data suggest that waste containment systems with liners and covers, when constructed and maintained in accordance with current regulations, are performing well thus far. However, they have not been in existence long enough to assess long-term (postclosure) performance, which may extend for hundreds of years. The book makes recommendations on how to improve future assessments and increase confidence in predictions of barrier system performance which will be of interest to policy makers, environmental interest groups, industrial waste producers, and industrial waste management industry.




Soil Reinforcement with Geotextiles

The Deep Mixing Method


Book Description

The Deep Mixing Method (DMM), a deep in-situ soil stabilization technique using cement and/or lime as a stabilizing agent, was developed in Japan and in the Nordic countries independently in the 1970s. Numerous research efforts have been made in these areas investigating properties of treated soil, behavior of DMM improved ground under static and d
