    This book discusses contemporary issues related to soil mechanics and foundation engineering in earthworks, which are critical components in construction projects and often require detailed management techniques and unique solutions to address failures and implement remedial measures. The geotechnical engineering community continues to improve the classical testing techniques for measuring critical properties of soils and rocks, including stress wave-based non-destructive testing methods as well as methods used to improve shallow and deep foundation design. To minimize failure during construction, contemporary issues and related data may reveal useful lessons to improve project management and minimize economic losses. This book focuses on these aspects using appropriate methods in a rather simple manner. It also touches upon many interesting topics in soil mechanics and modern geotechnical engineering practice such as geotechnical earthquake engineering, principals in foundation design, slope stability analysis, modeling in geomechanics, offshore geotechnics, and geotechnical engineering perspective in the preservation of historical buildings and archeological sites. A total of seven chapters are included in the book

    Engineering geology maps of the UK

    Get PDF
    School and university students of geology, engineering geology and geotechnical engineering generally have less knowledge of engineering geological conditions than those who have had experience of hands-on research or practice. In the UK, the number of geology, geoscience and earth science departments has reduced over the past 25 years. Engineering geology has a very weak academic base and geology is taught less to civil engineering students than previously

    Geotechnical Failures: an Excellent Tool to Teach Geotechnical Engineering

    It is well understood that geotechnical engineering is a branch of civil engineering that requires most engineering judgment. However, the question remains, how to effectively convey this to the students who are used to learn from typical lectures, using textbook approach, i.e., explanation of basic concepts by the course instructor, solution of a lot of example problems with assumed parameters having straight forward steps and definite answers, solution of additional similar problems by students as a part homework assignments, and traditional exams. Case histories of geotechnical failures could play an invaluable role in training the geotechnical engineers for 21st century. Southern Illinois University at Carbondale (SIUC) offers a unique 3 credit hour course on geotechnical engineering in professional practice which is entirely based on practical aspects of geotechnical engineering. The course contents include learning from geotechnical engineering case histories. This paper presents information about the course and how case histories are used to train geotechnical engineers at SIUC

    From Case Histories to Conceptual Models

    Geotechnical engineering deals with complicated and highly variable set of engineering principles. A typical geotechnical engineering project comprises site characterization, foundation / soil treatment design, execution, monitoring and quality control systems. Unlike some other civil engineering designs, highly variable soil conditions make a geotechnical designs an iterative and repetitive process which in-turn make these designs cost and time intensive. Economy and optimization of geotechnical designs are dependent on comprehensive site characterization and evaluation of multiple alternatives. Availability of up-to-date data sets of geotechnical case histories covering entire spectrum; from techniques / technologies to results can help reduce both cost and time of future geotechnical projects. Knowledge from case histories can be used to develop geotechnical constitutive and analytical models with the help of information technology; such models can lead us to many progressive and futuristic limits of geotechnical engineering. The authors of the paper intend to propose architectural development of “Geotechnical Information System (GTIS)”. The GTIS system covering fundamental geotechnical concepts, data of case histories such as; techniques, technologies employed, monitoring and quality control systems, results / effectiveness of techniques, will provide a framework for the following: • increased understanding of world-wide geotechnical issues by sharing lessons learnt which will help minimize barriers of uncertainty • enhancement of investigation and design procedures • development of economical and efficient technologies • identification of areas for collaborative research • development of “Geotechnical Artificial Intelligence Systems (GTAIS)

    Bioengineering Techniques for Soil Erosion Protection and Slope Stabilization

    The use of bio-engineering methods for soil erosion protection and slope stabilization has a long tradition. Old methods with rocks and plants, structures of timber have been used over the past centuries. Recently these old soil conservation and stabilization techniques have been rediscovered and improved. Biotechnical engineering methods have become part of geotechnical and hydraulic engineering and have helped bridge the gap between classical engineering disciplines, land use management, landscape architecture and biological sciences. In this paper the different uses of plants in hydraulic and geotechnical engineering design are presented. The core of this study is a comprehensive overview of the most important biotechnical construction methods used for soil erosion protection and slope stabilization. Methods, construction procedure, and the major advantages and disadvantages of these biotechnical methods are discussed. Considerations about construction and maintenance costs conclude in this paper.

    Teaching earth pressure theory using physical models: an example in civil engineering

    The transition from basic Engineering courses in the first year of Civil Engineering curriculum, into the analysis and design of Civil Engineering structures can be challenging for students. Indeed, most students find it difficult in learning some of the theoretical courses in later years of their engineering studies. In this paper, discussions will be directed to the role of physical models in assisting the teachings of advanced Civil Engineering courses. Examples of physical models will be shown by making use of those developed by the authors in the teaching of Geotechnical Engineering at University of Southern Queensland, Australia
