Book Description
Reinforced earth consists of a soil mass whose engineering characteristics and performance have been improved by the introduction of small quantities of frictional material that processes a relatively high tensile strength. The analysis of a reinforced earth system which incorporates metal strips placed at known intervals in the vertical and transverse directions within the soil mass is a complex problem. The complexity arises from the fact that reinforced earth is a three-dimensional problem and cannot be solved without imposing simplification with regard to the mechanical behavior of the system as well as the constitutive relationship governing the interaction between various components of the reinforced earth mass. The investigation reported herein describes a simplified approach for analyzing the instrumented reinforced earth wall which was previously constructed and loaded to failure at the U.S. Army Engineer Waterways Experiment Station. The three-dimensional problem was approximated by a structurally equivalent two-dimensional system and a two-dimensional finite element method was used in the analysis. The nonlinear behavior of the earth fill of the reinforced earth wall was simulated by hyperbolic formulation. The behavior of the metal skin element and reinforcing strips was assumed linear elastic until the yield stress was reached; thereafter, these metal components were assumed to fail plastically. Interface elements, to accommodate slippage between components of the reinforced earth wall, were also employed in the analysis. (Author).

Book Description
A simplified approach to applying the Finite Element Method to geotechnical problems Predicting soil behavior by constitutive equations that are based on experimental findings and embodied in numerical methods, such as the finite element method, is a significant aspect of soil mechanics. Engineers are able to solve a wide range of geotechnical engineering problems, especially inherently complex ones that resist traditional analysis. Applied Soil Mechanics with ABAQUS® Applications provides civil engineering students and practitioners with a simple, basic introduction to applying the finite element method to soil mechanics problems. Accessible to someone with little background in soil mechanics and finite element analysis, Applied Soil Mechanics with ABAQUS® Applications explains the basic concepts of soil mechanics and then prepares the reader for solving geotechnical engineering problems using both traditional engineering solutions and the more versatile, finite element solutions. Topics covered include: Properties of Soil Elasticity and Plasticity Stresses in Soil Consolidation Shear Strength of Soil Shallow Foundations Lateral Earth Pressure and Retaining Walls Piles and Pile Groups Seepage Taking a unique approach, the author describes the general soil mechanics for each topic, shows traditional applications of these principles with longhand solutions, and then presents finite element solutions for the same applications, comparing both. The book is prepared with ABAQUS® software applications to enable a range of readers to experiment firsthand with the principles described in the book (the software application files are available under "student resources" at www.wiley.com/college/helwany). By presenting both the traditional solutions alongside the FEM solutions, Applied Soil Mechanics with ABAQUS® Applications is an ideal introduction to traditional soil mechanics and a guide to alternative solutions and emergent methods. Dr. Helwany also has an online course based on the book available at www.geomilwaukee.com.

Book Description
A numerical model, simulating the complex behavior of reinforced soil walls using the finite element method, was developed to evaluate the behavior of a surcharged, geosynthetic-reinforced retaining wall with modular block facing. A nonlinear elastic-plastic constitutive soil material model was calibrated to experimental plane strain test data, while the performance of the wall model was validated against full-scale laboratory testing of an identical geosynthetic-reinforced wall. The results from both the constitutive model and the wall model were also compared to predictions made in the literature. It was found that the behavior of the reinforced soil wall was adequately represented by the numerical model at the end of construction and throughout the surcharge loading sequence. Furthermore, evaluation of the parametric analysis demonstrated the inter-dependencies and combined influence of various design parameters. Impacts of reinforcement spacing versus stiffness were investigated, along with stress distributions and load shedding relative to footing placement. Lateral earth pressures at the facing were compared to predictions from conventional design methods and measured loads in the reinforcement. The finite element model was also assessed of its ability to predict ultimate limit state conditions in reinforced soil 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.
