. Stresses in a Soil Mass. Geotechnical Engineering A Historical Perspective. Definitions of Key Terms are given which students may not have encountered previously, or may have been understood in a different context. Here a new theory is proposed for earth fissure formation in an unconfined aquifer based on fundamental soil mechanics principles, continuum mechanics, and fluid flow in porous media. However, progress in the area of geotechnical education has been rather slow. Origins of Soil and Grain Size.
Key Point summaries throughout emphasize the most important points in the material just read. Soil Mechanics Fundamentals lays a solid foundation on key principles of soil mechanics for application in later engineering courses as well as in engineering practice. An earth fissure can form at the surface and propagate downwards or it can form beneath the surface and propagate upwards. The latter has become a major worldwide issue in areas where groundwater is pumped for domestic, agricultural, and industrial use. Origins of Soil and Grain Size. Geological discontinuities are the preferred location for the formation of earth fissures. One type of simulation deals with the delivery of course con tent to better elucidate on selected basic concepts using interactive animations.
Earth fissures are initiated in aquifer sediments from bending and shear failure on vertical planes. Plasticity and Structure of Soil. Lateral Earth Pressure: Curved Failure Surface. The outputs from numerical methods are often overwhelming and one has to wade through a large body of numbers to get the desired results. The simula tions are integrated into an interactive multimedia courseware that contains interactive problem solving, electronic quizzes, a glossary, notation, a notepad, and computer program utilities in ad dition to the virtual laboratory and interactive animations of the selected topics. The cause of earth fissure formation in the sediments within the aquifer differs from that of sediments above the aquifer. Lateral Earth Pressure: At-Rest, Rankine, and Coulomb.
In this paper, simulations to enhance learning and retention in a course in Civil Engineering Soil Mechanics are presented. The author discusses and demonstrates contemporary ideas and methods of interpreting the physical and mechanical properties of soils for both fundamental knowledge and for practical applications. Numerical methods, especially the finite element method, are widely used in geotechnical engineering to analyze a large range of boundary value problems. Plasticity and Structure of Soil.

The purpose of this paper is to present visualization techniques to help students understand fundamental concepts in geotechnical analysis. Stresses in a Soil Mass. Earth fissures are approximately vertical cracks in the ground. With this textbook, students will learn how to conduct a site investigation, acquire an understanding of the physical and mechanical properties of soils and methods of determining them, and apply the knowledge gained to analyse and design earthworks, simple foundations, retaining walls and slopes. This accessible, clear and concise textbook strikes a balance between theory and practical applications for an introductory course in soil mechanics for undergraduates in civil engineering, construction, mining and geological engineering. Lateral Earth Pressure: Curved Failure Surface. Go to and type solution manual or test bank name you want in search box.
Soil-Bearing Capacity for Shallow Foundations. Lateral Earth Pressure: At-Rest, Rankine, and Coulomb. Prelimi nary evaluations indicate that simulations can significantly enhance the presentation of some topics and improve learning and retention. Earth fissures are initiated in the sediments above the aquifer when the shear strains cause the soil to fail along vertical planes. Background information needed to support study in later design-oriented courses or in professional practice is provided through a wealth of comprehensive discussions, detailed explanations, and more figures and worked out problems than any other text in the market. Various theories, mostly conceptual, have been proposed to describe the formation of earth fissures due to groundwater level decline. These visual outputs help to improve our interpretation and evaluation of numerical analyses.
Background information needed to support study in later design-oriented courses or in professional practice is provided through a wealth of comprehensive discussions, detailed explanations, and more figures and worked out problems than any other text in the market. Software technology is now available to animate the results of numerical methods to provide visual outputs. This theory shows that the most efficient mechanism for earth fissure formation is a combination of bending and shearing. The findings from this model are in contrast to current conceptual models, which are based on tensile strains observed in existing earth fissures.

Another type of simulation deals with the development of a vir tual laboratory in which the student can conduct laboratory tests and interpret the results as if they were in a real laboratory. In this paper, a multimedia interactive and animated teaching module on the basic concepts of one-dimensional consolidation of soils using a finite difference scheme is presented.
Soil-Bearing Capacity for Shallow Foundations. The simulations were developed using various royalty-free, com mercial software such as Authorware. They are caused by natural events such as earthquakes or by human activities such as groundwater level decline due to pumping. Key learning objectives are described and then self-paced interactions are developed to meet these objectives. Geotechnical Engineering — A Historical Perspective. The chapter presentation and content is informed by modern theories of how students learn: Learning objectives inform students what knowledge and skills they are expected to gain from the chapter.
