This book was released on 1986 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seismic refraction surveys are a valuable tool for shallow engineering site characterization purposes. Standard refraction analysis uses first arrival time data to interpret subsurface layer velocities and thicknesses. In spite of their usefulness, refraction surveys suffer from several shortcomings. In this study, the practical influence of one of these shortcomings, the thin layer effect, was examined. Synthetic seismograms were computed, using the reflectivity method, for several thin layer models. These synthetic record sections were then treated as field data and the standard interpretation processes were performed. Significant discrepancies were observed in many cases between the true geologic model originally input to the code and the model interpreted from the synthetic record sections. Keywords: Primary waves(seismic waves), Seismic refraction, Wavelength, Synthetic seismograms, Geologic models, Thin layers.

Download or read book Shallow Refraction Seismics written by Bengt Sjogren and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are many general geophysical textbooks dealing with the subject of seismic refraction. As a rule, they treat the principles and broad aspects ofthe method comprehensively but problems associated with engineering seismics at shallow depths are treated to a lesser extent. The intention of this book is to emphasize some practical and theoretical aspects of detailed refraction surveys for civil engineering projects and water prospecting. The book is intended for students of geophysics, professional geophysicists and geologists as well as for personnel who, without being directly involved in seismic work, are planning surveys and evaluating and using seismic results. The latter category will probably find Chapters 1, 5 and 6 of most interest. Interpretation methods, field work and interpretation of field examples constitute the main part of the book. When writing I have tried to concentrate on topics not usually described in the literature. In fact, some discussions on interpretation and correction techniques and on sources of error have not been published previously. The field examples, which are taken from sites with various geological conditions, range from simple to rather complicated interpretation problems. Thanks are due to A/S Geoteam (Norway), Atlas Copco ABEM AB (Sweden), BEHACO (Sweden) and the Norwegian Geotechnical Institute for allowing me to use field examples and certain data from their investigations. I should particularly like to thank Professor Dattatray S. Parasnis of the University of Luleii (Sweden) for revising the manuscript and for his numerous invaluable suggestions.

Available in PDF, EPUB and Kindle. Book excerpt: This reference manual is designed to enable more geophysicists to appreciate static corrections, especially their limitations, their relationship with near-surface geology, and their impact on the quality of final interpreted sections. The book is addressed to those involved in data acquisition (datum static corrections), data processing (datum static and residual static corrections), and interpretation (the impact that unresolved static corrections, especially the long-wavelength or low-spatial-frequency component, have on the interpretation of the final section). Simple explanations of the underlying principles are included in an attempt to remove some of the mystique of static corrections. The principles involved are illustrated with simple models; these are supplemented with many data examples. This book details differences in approaches that must be considered among 2D, 3D, and crooked-line recordings as well as between P-wave and S-wave surveys. Static corrections are shown to be a simplified yet practical approach to modeling the effects of the near surface where a more correct wavefield or raypath-modeled method may not be efficiently undertaken. Chapters cover near-surface topography and geology; computation of datum static corrections; uphole surveys; refraction surveys; static corrections-limitations and effect on seismic data processes; residual static corrections; and interpretation aspects. An extensive index and a large list of references are included.
