Product Description
This proceedings, "Analysis and Design of Retaining Structures Against Earthquakes", contains both invited and contributed papers, which focus on the questions of dynamic earth pressures on fixed and movable rigid and flexible walls; displacements in translation and rotation of walls under earthquakes; behavior of fills and abutments during earthquake; and centrifuge tests on walls. Both analytical and experimental data have been presented on possible behavior of retaining structures under seismic loading. A study of this volume and other published literature shows considerable effort is being devoted to determination of realistic dynamic pressures, displacement in translation and rotation of retaining structures and behavior of fills for abutments. Since a synthesis of these studies is not currently available, there are no unified and generally acceptable solutions to the above questions. However, the discussions and presentations of the papers during the session does highlight the need for such solutions and more definite descriptions of unsolved problems. ... Read more

Product Description
The papers in this Geotechnical Special Publication explain and demonstrate a broad range of methods of probabilistic site characterization using soil data obtained at one or more National Geotechnical Experimentation Sites (NGES), in particular the NGES locations at Texas A&M University, Treasure Island Naval Station, University of Massachusetts at Amherst, University of Houston, and Northwestern University. Among the topics covered are statistical estimation procedures based on homogenous random field theory, with as parameters the mean, coefficient of variation and scale of fluctuation, as well as two alternate fractal representations of spatial variation in soil deposits, a neural network model, and an approach to correlating soil properties based on the concept of fuzzy subsets. The aim of this publication is to provide both a state-of-the-art assessment of statistical methods of soil profile modeling and a set of baseline statistics, representative of the well-documented NGES, intended to serve as a priori information for probabilistic site characterization. ...

Product Description
This proceedings, "Fracture Mechanics Applied to Geotechnical Engineering", contains theoretical and experimental studies related to the formation, propagation, and interaction of cracks in clays, cemented and grouted sands, rocks, and pavement materials. A review of the origin and classification of fissures in clays is presented. Previous studies that make use of fracture mechanics theory to interpret the propagation mechanics of cracks in clay are included. One study deals with the use of the Mohr-Coulomb failure criterion to interpret the cracking of earth dams. Also included are papers that make use of fracture mechanics theory to understand the propagation of cracks in samples of clay, grouted sand, and asphalt pavements. Fracture mechanics theory is used to obtain the depth of cracks in soils subjected to drying. Also included are studies that make use of the finite element and discrete element methods to interpret the formation and propagation mechanisms of cracks in brittle and plastic clays, clay covers in landfills, and cemented sands.A study of the acoustic emissions signals emanating from a rock sample containing a crack under Mode I, II, or III type of loading is also presented. ...
