This book was released on 2021 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Shear Wave Velocity Profile Database (VSPDB) was developed in prior work to archive and disseminate data from sites with shear wave velocity (VS) profiles, including seismic velocities, soil stratigraphic information, and penetration resistances. The VSPDB is organized as a structure query language (SQL) relational database and is populated to date mainly with data from California. The first major component of this project was to augment the database with information from 30 bridge sites in California with 251 borehole logs and 88 VS profiles. The information was obtained from the California Department of Transportation (Caltrans) and translated into unified machine-readable formats via a computed program (UNIFY). The second major component of this project was related to VS prediction models. A number of models were reviewed and conditioned on penetration resistance, depth, and soil type parameters. A major distinguishing characteristic of available models is whether they allow for different levels of VS and penetration resistance scaling with depth (or overburden stress). I selected a model by Brandenberg et al. (2010) for validation against VSPDB data, which includes differential scaling features. That SPT-based model was developed and recommended by Building Seismic Safety Council for VS prediction for California sites. Querying of the VSPDB led to 2453 data pairs (1415 for sand, 641 for clay, and 397 for silt) consisting of all predictor variables (penetration resistance, depth, soil type) and VS values. Plots of data trends relative to model predictions were examined, and residuals analyses were performed to investigate potential model biases and whether the data requires different levels of scaling with N60-values or overburden pressure. The results indicate that the model overpredicts VS for all three soil types (sand, clay, and silt) but mainly for clay. The scaling of VS with N60 is stronger from the data for sand but not the other soil types. No adjustments to overburden scaling were required. Adjusted model coefficients based on the data analyses are provided.
Book Synopsis Vertical Shear-wave Velocity Profiles Generated from Spectral Analysis of Surface Waves by : Dr. Neil Anderson
Download or read book Vertical Shear-wave Velocity Profiles Generated from Spectral Analysis of Surface Waves written by Dr. Neil Anderson and published by . This book was released on 2003 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface wave (Rayleigh wave) seismic data were acquired at six separate bridge sites in southeast Missouri. Each acquired surface wave data set was processed [spectral analysis of surface waves (SASW)] and transformed into a site-specific vertical shear-wave velocity profile (SASW shear-wave velocity profile). The SASW shear-wave velocity profiles generated for each bridge site were compared to other geotechnical data including seismic cone penetrometer shear-wave velocity profiles, cross-borehole shear-wave velocity profiles, and borehole lithology logs. The geotechnical data presented herein indicate the SASW shear-wave velocity profiles correlate well with subsurface lithology logs and available cross-borehole shear-wave velocity control. More specifically, clays, silts and sands exhibit relatively characteristic SASW shear-wave velocities, which increase incrementally with increasing depth of burial. The authors believe these correlations demonstrate that SASW shear-wave velocities are reliable.

This book was released on 2019-01-20 with total page 717 pages. Available in PDF, EPUB and Kindle. Book excerpt: We live on a dynamic Earth shaped by both natural processes and the impacts of humans on their environment. It is in our collective interest to observe and understand our planet, and to predict future behavior to the extent possible, in order to effectively manage resources, successfully respond to threats from natural and human-induced environmental change, and capitalize on the opportunities â€" social, economic, security, and more â€" that such knowledge can bring. By continuously monitoring and exploring Earth, developing a deep understanding of its evolving behavior, and characterizing the processes that shape and reshape the environment in which we live, we not only advance knowledge and basic discovery about our planet, but we further develop the foundation upon which benefits to society are built. Thriving on Our Changing Planet presents prioritized science, applications, and observations, along with related strategic and programmatic guidance, to support the U.S. civil space Earth observation program over the coming decade.

Book Synopsis National Earthquake Resilience by : National Research Council
Download or read book National Earthquake Resilience written by National Research Council and published by National Academies Press. This book was released on 2011-09-09 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States will certainly be subject to damaging earthquakes in the future. Some of these earthquakes will occur in highly populated and vulnerable areas. Coping with moderate earthquakes is not a reliable indicator of preparedness for a major earthquake in a populated area. The recent, disastrous, magnitude-9 earthquake that struck northern Japan demonstrates the threat that earthquakes pose. Moreover, the cascading nature of impacts-the earthquake causing a tsunami, cutting electrical power supplies, and stopping the pumps needed to cool nuclear reactors-demonstrates the potential complexity of an earthquake disaster. Such compound disasters can strike any earthquake-prone populated area. National Earthquake Resilience presents a roadmap for increasing our national resilience to earthquakes. The National Earthquake Hazards Reduction Program (NEHRP) is the multi-agency program mandated by Congress to undertake activities to reduce the effects of future earthquakes in the United States. The National Institute of Standards and Technology (NIST)-the lead NEHRP agency-commissioned the National Research Council (NRC) to develop a roadmap for earthquake hazard and risk reduction in the United States that would be based on the goals and objectives for achieving national earthquake resilience described in the 2008 NEHRP Strategic Plan. National Earthquake Resilience does this by assessing the activities and costs that would be required for the nation to achieve earthquake resilience in 20 years. National Earthquake Resilience interprets resilience broadly to incorporate engineering/science (physical), social/economic (behavioral), and institutional (governing) dimensions. Resilience encompasses both pre-disaster preparedness activities and post-disaster response. In combination, these will enhance the robustness of communities in all earthquake-vulnerable regions of our nation so that they can function adequately following damaging earthquakes. While National Earthquake Resilience is written primarily for the NEHRP, it also speaks to a broader audience of policy makers, earth scientists, and emergency managers.
