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. Geotechnical and Geophysical Site Characterization 4 will be much of interest to academics, engineers and professionals involved in Geotechnical Engineering.
Geotechnical and Geophysical Site Characterization collects the papers presented at the Third International Conference on Site Characterization (ISC’3) that took place in Taipei from April 1-4, 2008. The subjects covered include new developments in mechanical in-situ testing and interpretation techniques, statistical analysis of test data, geo-environmental site characterization, soil sampling methods, multi-dimensional geophysical imaging techniques, residual/unsaturated soil characterization, and case histories that involve major construction projects or disaster investigations. Over 200 papers, twelve keynote lectures and the third Mitchell lecture were presented at the conference. Geotechnical and Geophysical Site Characterization provides a wealth of valuable information for practicing engineers as well as researchers worldwide.

In earthquake-prone regions of the world it is important not only to ensure that new facilities meet optimal standards but also that existing structures and infrastructure be retrofitted and rehabilitated. As world populations concentrate in urban areas, the stakes in human life and property of such natural disasters as earthquakes becomes higher and higher. This has been driving research on advances in the field. These advances are presented biennially at a conference organised by the Wessex Institute of Technology.The advances presented at the ninth conference in the series, which began in 1991 are presented in this book. 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.
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 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.

Site and Geomaterial Characterization addresses issues ranging from the micro-characterization of processes to the in situ evaluation of engineering properties of soils. This Geotechnical Special Publication contains over 40 technical papers that were presented at the GeoShanghai Conference held in Shanghai, China from June 6-8, 2006. This book is divided into four main sections, with all of the papers addressing one of the greatest challenges in geotechnical engineering research and practice: the evaluation of geomaterial properties with minimal to no disturbance states. The first section includes the general theme paper by James K. Mitchell, University Distinguished Professor, Emeritus, Virginia Polytechnic Institute and State University, who focuses on the study of physico-chemical behavior of soils, soil improvement and geomaterial characterization. The second section is completely devoted to recognizing the services of Dr. Mehmet T. Tumay, Georgia Gulf Distinguished Professor Emeritus in the Department of Civil and Environmental Engineering at Louisiana State University, for his immense contribution to research and practice in geotechnical engineering. The third section covers non-destructive evaluation and geophysical testing to address soil characterization problems relevant to foundation exploration, geoenvironmental evaluation and earthquake related topics. Finally, the fourth section contains other in situ testing methods that deal with the analysis of field data and interpretation of soil properties, as well as simulation of in situ testing using numerical methods.
