Book excerpt: The Multi-Channel Analysis of Surface Waves (MASW) is a technique in which surface waves can be analyzed to determine soil shear wave velocity profiles with depth. The shear wave velocity of soil can be used to calculate the shear modulus, which is an important geotechnical engineering parameter. Site surveys were conducted and analyzed located at a location on the flood plain of the Tennessee River. The flood plain consists of a thin layer of soil above rigid (Knox Dolomite) bedrock and exhibited strong stratification. Three different aspects of MASW data acquisition and analysis are presented in the study. The first aspect is the response correction of the classical horizontal and vertical component geophone and its effects on surface wave dispersion; the second aspect is the effect of Rayleigh wave MASW data acquisition, analysis, and modeling as influenced by Rayleigh wave guides; the third aspect is the use of MASW and Love wave data acquisition, analysis, and modeling. MASW is performed using a seismic source and geophones (velocity sensor) without correcting the amplitude and phase errors induced by the equivalent single degree of freedom response function representing the mechanical response of a given velocity sensor. Geophones were experimentally tested in the laboratory to determine their natural frequency, damping ratio, and transduction constants. The results from these tests were mathematically corrected for their mechanical response and compared to uncorrected and corrected field data. Several seismic sources and various sourceoffset distances were evaluated to determine their effects on Rayleigh wave dispersion. Rayleigh waves, guided in a layer, were interpreted to have a profound influence on the Rayleigh wave dispersion data obtained using different seismic sources and source-offset distances. Results from Love wave data analysis produced superior dispersion data in comparison to the dispersion data obtained from Rayleigh wave data, making interpretation much more certain.

Available in PDF, EPUB and Kindle. Book excerpt: "Soils and rocks are complex natural geomaterials that exhibit a wide range in strength, stiffness, state of stress, structure, and flow characteristics. Geotechnical & Geophysical Site Characterization provides eleven keynote state-of-the-art papers, including the Mitchell Lecture. A total selection of 219 technical papers and theme reports address methods of site exploration related to ground exploration for civil engineering and construction works. These two volumes represent a collection of experience & knowledge regarding various methods of in-situ testing, geophysical techniques, innovative devices, improved interpretation algorithms, and statistical treatment of field data for the characterization of soils, rocks, and other geomaterials. The papers represent the written records and documented efforts from international experts from industry, academe, and government who participated in the Second International Conference on Site Characterization held in Porto, Portugal on September 20-22, 2004. Topics include the utilization of rotary drilling, sampling, and coring techniques. Of particular interest is the variety of in-situ tests, including standard penetration, cone penetration, flat dilatometer, pressuremeter, vane shear, piezocone, dynamic probes, and specialized tools, as well as geophysical approaches: resistivity surveys, surface waves, crosshole, downhole, electromagnetic conductivity, and ground penetrating radar. A careful and proper site evaluation is required in the analysis and design of new structures, construction monitoring, and forensic studies that require remediation. Many of the contributions relate to case studies of projects that involve shallow foundations, drilled shafts, pilings, slope stability, excavations, earth dams, tunnels, and mining. Several papers discuss a combined approach using multiple methods and/or complementary set of geotechnical & geophysical tests to ascertain the characteristics of the ground."--back cover.

This book was released on 2020-06-20 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book bridges the gap between theory and practice, showing how a detailed definition of the shear-wave velocity (VS) profile can be efficiently obtained using limited field equipment and following simple acquisition procedures. It demonstrates how surface waves (used to define the VS profile) and vibration data (used to describe the dynamic behaviour of a building) can be recorded using the same equipment, and also highlights common problems, ambiguities and pitfalls that can occur when adopting popular methodologies, which are often based on a series of simplistic assumptions. Today, most national and international building codes take into account a series of parameters aimed at defining the local seismic hazard. Sites are characterised based on the local VS profile, and the dynamic behaviour of existing buildings is defined through the analysis of their eigenmodes. The book includes a series of case studies to help readers gain a deeper understanding of seismic and vibration data and the meaning (pros and cons) of a series of techniques often referred to as MASW, ESAC, SPAC, ReMi, HVSR, MAAM and HS. It also provides access to some of the datasets so that readers can gain a deeper and more concrete understanding of both the theoretical and practical aspects.

Available in PDF, EPUB and Kindle. Book excerpt: Protecting the natural environment and promoting sustainability have become important objectives, but achieving such goals presents myriad challenges for even the most committed environmentalist. American Environmentalism: Philosophy, History, and Public Policy examines whether competing interests can be reconciled while developing consistent, coherent, effective public policy to regulate uses and protection of the natural environment without destroying the national economy. It then reviews a range of possible solutions. The book delves into key normative concepts that undergird American perspectives on nature by providing an overview of philosophical concepts found in the western intellectual tradition, the presuppositions inherent in neoclassical economics, and anthropocentric (human-centered) and biocentric (earth-centered) positions on sustainability. It traces the evolution of attitudes about nature from the time of the Ancient Greeks through Europeans in the Middle Ages and the Renaissance, the Enlightenment and the American Founders, the nineteenth and twentieth centuries, and up to the present. Building on this foundation, the author examines the political landscape as non-governmental organizations (NGOs), industry leaders, and government officials struggle to balance industrial development with environmental concerns. Outrageous claims, silly misrepresentations, bogus arguments, absurd contentions, and overblown prophesies of impending calamities are bandied about by many parties on all sides of the debate—industry spokespeople, elected representatives, unelected regulators, concerned citizens, and environmental NGOs alike. In lieu of descending into this morass, the author circumvents the silliness to explore the crucial issues through a more focused, disciplined approach. Rather than engage in acrimonious debate over minutiae, as so often occurs in the context of "green" claims, he recasts the issue in a way that provides a cohesive look at all sides. This effort may be quixotic, but how else to cut the Gordian knot?

Book excerpt: Surface wave methods analysis the dispersive nature of surface wave propagation in heterogeneous media to measure shear wave velocity or material damping ratio profiles, and enable earthquake site response to be assessed. This is the only comprehensive reference that provides a unified treatment of surface wave propagation, signal processing, inverse theory and the testing protocols that form the basis of modern surface wave methods. The use of these tests has increased dramatically since the 1980s, but they are too often performed and interpreted in a variety of ways that are confusing. This book answers the pressing need for a guide to the basic principles as well as outlining a set of reliable, dependable and accepted practices. It is written for geotechnical engineers, engineering seismologists and geophysicists as well as academics in these fields.

Book excerpt: Just a few meters below the Earth's surface lie features of great importance, from geological faults which can produce devastating earthquakes, to lost archaeological treasures. This refreshing, up-to-date book explores the foundations of interpretation theory and the latest developments in near-surface techniques, used to complement traditional geophysical methods for deep-exploration targets. Clear but rigorous, the book explains theory and practice in simple physical terms, supported by intermediate-level mathematics. Techniques covered include magnetics, resistivity, seismic reflection and refraction, surface waves, induced polarization, self-potential, electromagnetic induction, ground-penetrating radar, magnetic resonance, interferometry, seismoelectric and more. Sections on data analysis and inverse theory are provided and chapters are illustrated by case studies, giving students and professionals the tools to plan, conduct and analyze a near-surface geophysical survey. This is an important textbook for advanced-undergraduate and graduate students in geophysics and a valuable reference for practising geophysicists, geologists, hydrologists, archaeologists, and civil and geotechnical engineers.
