1st Edition
by Jonathan T. H. Wu (Author)
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.
