Site characterization is a fundamental step towards the proper design, construction and long term performance of all types of geotechnical projects, ranging from foundation, excavation, earth dams, embankments, seismic hazards, environmental issues, tunnels, near and offshore structures. The Fourth International Conference on Site Characterization (ISC’4) was held in Porto de Galinhas, Pernambuco,Brazil, from 18 to 21 September 2012, under the responsibility of TC-102/TC-16 on In-Situ Testing of the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE), the Brazilian Society for Soil Mechanics and Geotechnical Engineering (ABMS), and the Federal University of Pernambuco, Brazil (UFPE). Financial support of ISC4 was provided by the Brazilian National Science and Education Councils (CNPq, CAPES and FACEPE), sponsors and exhibitors and other organizations and companies. The fourth conference followed the successful series of international conferences held in Atlanta (ISC-1, 1998), Porto (ISC-2, 2004), and Taipei (ISC-3, 2008). ISC’4 congregated several researchers, geotechnical engineers, and practitioners from all over the world involved with the conference general themes, namely practical application of novel and innovative technologies in geotechnical and geophysical engineering, along with their interpretation and utilization for the purposes of site characterization. The two volumes making up Geotechnical and Geophysical Site Characterization 4 contain 8 keynote Lectures prepared by experts in the field, including the 5th James K. Mitchell Lecture presented by Dr. Peter K. Robertson, and 4 Workshop Lectures and 217 technical papers from 40 different countries. The books are divided into 11 general themes: 1. Direct-push and Borehole-type in-situ test; 2. Development of new equipment and methods; 3. New approaches for interpreting data; 4. Applications to shallow and deep foundations; 5. Special uses of in-situ tests; 6. Site investigation for infrastructure projects; 7. Geophysical; 8. Seismic ground hazards; 9. Investigation in very soft to extremely soft soils; 10. Non-textbook type geomaterials; 11. Environmental geotechnics.

The papers cover Plates and other geological risks; Earthquake prediction; Microzoning; Remote sensing / Monitoring / Early warning systems; Seismic codes; Seismic hazard and vulnerability; Tsunamis; Seismic isolation and energy dissipation; Structural dynamics; Building performance during earthquakes; Retrofitting; Lifelines; Material mechanics and characterisation; Nonlinear numerical analysis; Performance based design; Experimental studies; Forensic analysis; Safety and security; Socio-economic issues; Insurance related issues; Innovative technologies; Case studies.

Earthquake Ground Motion

Author: S. Syngellakis
Publisher: WIT Press
ISBN: 9781784660000
Release Date: 2014-09-29
Genre: Science

The best way to minimize damage from earthquakes is to predict their location and effects and reinforce against those possible effects. Toward that end, this book presents prediction methods useful for the design of earthquake-resistant structures. In the first of two parts, the book deals with issues relating to the characterisation and the rational definition of seismic input. It begins with a study of earthquake records that leads to the identification of their damage potential parameters, such as the peak ground acceleration and the strong motion duration. Subsequent chapters concern themselves with the deterministic and probabilistic methodologies for producing seismic inputs. Further chapters are dedicated to the generation of artificial seismic input on the basis of stochastic or probabilistic approaches. The second part of this volume deals with the effects of ground motion on foundation elements and structural integrity. Particular emphasis is given to the interaction of foundation piles with vibrating soils, homogeneous or heterogeneous. The final two chapters are concerned with the possible connection between soil structure interaction (SSI) and structural damage. In both instances records of actual earthquake induced motion are used for such assessments.

Landslides in Sensitive Clays

Author: Jean-Sébastien L'Heureux
Publisher: Springer Science & Business Media
ISBN: 9789400770799
Release Date: 2013-09-17
Genre: Nature

Landslides in sensitive clays represent a major hazard in the northern countries of the world such as Canada, Finland, Norway, Russia, Sweden and in the US state of Alaska. Past and recent examples of catastrophic landslides at e.g. Saint-Jean-Vianney in 1971, Rissa in 1979, Finneidfjord in 1996 and Kattmarka in 2009 have illustrated the great mobility of the remolded sensitive clays and their hazardous retrogressive potential. These events call for a better understanding of landslide in sensitive clay terrain to assist authorities with state-of-the-art hazard assessment methods, risk management schemes, mitigation measures and planning. During the last decades the elevated awareness regarding slope movement in sensitive clays has led to major advances in mapping techniques and development of highly sophisticated geotechnical and geophysical investigation tools. Great advances in numerical techniques dealing with progressive failure and landslide kinematic have also lead to increase understanding and predictability of landslides in sensitive clays and their consequences. This volume consists of the latest scientific research by international experts dealing with geological, geotechnical and geophysical aspects of slope failure in sensitive clays and focuses on understanding the full spectrum of challenges presented by landslides in such brittle materials.

Engineering Geology for Tomorrow s Cities

Author: M. G. Culshaw
Publisher: Geological Society of London
ISBN: 1862392900
Release Date: 2009-01-01
Genre: Science

This book and the accompanying DVD provide a statement of our knowledge and understanding of engineering geology as applied to the urban environment at the start of the 21st century. In particular, this volume demonstrates that: working standards originally developed nationally are becoming internationalized; risk assessment, rather than just assessment of hazards, is driving decision-making; geo-environmental change, whether climatically or anthropogenically driven, is becoming better understood; greater use of underground space is being made; the relentless advance of information technology is providing new opportunities for engineering geologists to interpret and visualize the subsurface. This book shows that in developed and developing countries alike, engineering ge-ologists are increasingly exchanging ideas and learning from each other in a genuine two-way process. These ideas will contribute significantly to the sustainable development of both new and long-established urban environments worldwide.

Theoretische Bodenmechanik

ISBN: 9783642532443
Release Date: 2013-03-13
Genre: Technology & Engineering

2 nung der durch Änderungen in der Belastung und in den Entwässe rungsbedingungen verursachten Wirkungen meist nur sehr gering sind. Diese Feststellung gilt im besonderen Maße für alle jene Auf gaben, die sich mit der Wirkung des strömenden Wasser befassen, weil hier untergeordnete Abweichungen in der Schichtung, die durch Probebohrungen nicht aufgeschlossen werden, von großem Einfluß sein können. Aus diesem Grunde unterscheidet sich die Anwendung der theoretischen Bodenmechanik auf den Erd- und Grundbau ganz wesentlich von der Anwendung der technischen Mechanik auf den Stahl-, Holz- und Massivbau. Die elastischen Größen der Baustoffe Stahl oder Stahlbeton sind nur wenig veränderlich, und die Gesetze der angewandten Mechanik können für die praktische Anwendung ohne Einschränkung übertragen werden. Demgegenüber stellen die theoretischen Untersuchungen in der Bodenmechanik nur Arbeits hypothesen dar, weil unsere Kenntnisse über die mittleren physikalischen Eigenschaften des Untergrundes und über den Verlauf der einzelnen Schichtgrenzen stets unvollkommen und sogar oft äußerst unzuläng lich sind. Vom praktischen Standpunkt aus gesehen, sind die in der Bodenmechanik entwickelten Arbeitshypothesen jedoch ebenso an wendbar wie die theoretische Festigkeitslehre auf andere Zweige des Bauingenieurwesens. Wenn der Ingenieur sich der in den grundlegen den Annahmen enthaltenen Unsicherheiten bewußt ist, dann ist er auch imstande, die Art und die Bedeutung der Unterschiede zu er kennen, die zwischen der Wirklichkeit und seiner Vorstellung über die Bodenverhältnisse bestehen.

Mechanical Engineering and Technology

Author: Tianbiao Zhang
Publisher: Springer Science & Business Media
ISBN: 9783642273292
Release Date: 2012-02-22
Genre: Computers

The volume includes a set of selected papers extended and revised from the 2011 International Conference on Mechanical Engineering and Technology, held on London, UK, November 24-25, 2011. Mechanical engineering technology is the application of physical principles and current technological developments to the creation of useful machinery and operation design. Technologies such as solid models may be used as the basis for finite element analysis (FEA) and / or computational fluid dynamics (CFD) of the design. Through the application of computer-aided manufacturing (CAM), the models may also be used directly by software to create "instructions" for the manufacture of objects represented by the models, through computer numerically controlled (CNC) machining or other automated processes, without the need for intermediate drawings. This volume covers the subject areas of mechanical engineering and technology, and also covers interdisciplinary subject areas of computers, communications, control and automation. We hope that researchers, graduate students and other interested readers benefit scientifically from the book and also find it stimulating in the process.
