Download or read book Detection of Subsurface Cavities written by Edward R. Bates and published by . This book was released on 1973 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research has been in progress since July 1970 to determine which geophysical and remote-sensing methods offer the most promising results for detecting subsurface cavities and what might be done to further develop them. Through extensive field tests, it has been determined that none of the standard electrical resistivity procedures give consistently good results. As a result of the initial field testing, a new process of data interpretation has been developed for one specific electrode configuration. Cavities less than 10 feet in diameter and at the depths greater than 100 feet were located. Research is continuing to adapt this process for locating water- or mud-filled cavities.

Book Synopsis Geotechnical and Geophysical Site Characterization by : António Viana da Fonseca
Download or read book Geotechnical and Geophysical Site Characterization written by António Viana da Fonseca and published by . This book was released on 2004 with total page 1082 pages. 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.

Available in PDF, EPUB and Kindle. Book excerpt: The research is part of a program underway to evaluate remote sensing instrumentation and methods for locating subsurface cavities that can cause serious highway construction and maintenance problems. Three methods of subsurface cavity detection based on different geophysical techniques were experimentally evaluated, including ground-penetrating radar, gravity profiling, and earth resistivity profiling. Tests were conducted at three sites having different geological environments. Verification tests showed all methods to be capable of locating air-filled cavities.

Download or read book Cavity Detection and Delineation Research. Report 2. Seismic Methodology: Medford Cave Site, Florida written by Joseph R Curro (Jr) and published by . This book was released on 1983 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of a research program designed to find a quick and economical methodology to detect and delineate cavities, seismic technology was applied to the cavity problem at the Medford Cave site, Florida. Six seismic techniques consisting of surface refraction, constant-spacing, fan-shooting, surface shear-wave, uphole refraction, and crosshole investigations were employed at the site in an effort to detect and delineate cavity features. The results of these tests indicated that the surface refraction, constant-spacing, and crosshole techniques detected and partially delineated cavities. Their degrees of success varied. In summary, the constant-spacing technique is the only surface seismic test procedure recommended for use in cavity detection-delineation and the crosshole P-wave technique is the only subsurface method recommended.
Book Synopsis Limits and Ability of the Multichannel Analysis of Surface Waves Method to Detect and Resolve Subsurface Anomalies by : Ugur Arslan
Download or read book Limits and Ability of the Multichannel Analysis of Surface Waves Method to Detect and Resolve Subsurface Anomalies written by Ugur Arslan and published by . This book was released on 2020 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: The multichannel analysis of surface waves (MASW) method is a non-invasive surface wave method used to characterize the layering and stiffness of the subsurface. This study assesses the practical limitations of using the MASW method for detecting and resolving subsurface anomalies. The sensitivity of MASW dispersion data to the presence of subsurface anomalies is examined through various two-dimensional (plane-strain) finite-difference elastic wave-propagation simulations. These simulations were performed on models containing anomalies of varying size, stiffness, and depth. The misfit between the dispersion data from a model with an anomaly (treatment model) and the same model without an anomaly (control model) were compared as a quantitative means of discerning if the anomaly was reliably detectable (i.e., outside the bounds of common dispersion data uncertainty). Those models categorized as containing a detectable anomaly, based on their experimental dispersion data, were further studied to determine if the dispersion data could be inverted to accurately resolve the anomaly’s size, stiffness, and depth. To rigorously perform the inversions, the procedures recommended by the surface wave inversion workflow SWinvert were adopted. These inversion procedures involve using multiple large-scale global-search inversions to address the problem’s non-linearity and multiple layering parameterizations to address the problem’s non-uniqueness. Following the inversion process, the shear wave velocity (Vs) profiles from the single “best” trial model associated with each layering parameterization were compared to the 1D Vs profiles from the centerline of the true/control model using an error function to quantitatively assess the ability of the MASW method to accurately resolve subsurface anomalies. In this study, anomalies with lateral extents less than approximately 1⁄2 the MASW array length located at depths greater than 5 m could not be resolved accurately by using MASW, even when the anomalies were relatively thick (> 2 m) and the impedance contrasts were notably high (> 2). The ability of MASW to detect an anomaly of a given size, stiffness, and depth is summarized in normalized figures, which are intended as a feasibility tool for those seeking to use MASW for anomaly detection
