This book was released on 2019-10-30 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: GEOPHYSICAL APPROACHES IN GEOLOGICAL STRUCTURE ASSESSMENT This book illustrates how geophysical methods can be used in subsurface investigations and exposed outcrops. It was written to share the knowledge of geophysical approaches (2-D resistivity, seismic refraction and ground magnetic) applied in making assessments towards geological structures. Furthermore, it presents, in detail, the importance of these methods in delineating the subsurface features with the purpose of enhancing the comprehension regarding the knowledge and concepts of the geophysical methods. This book accordingly compiles several case studies to capture the readers' interests and to ease their understanding. The geophysical methods used are non-destructive, rapid, relatively economic, and can vastly improve the characterization of the subsurface features. The correlation with geological parameters is used to validate the geophysical results for improved interpretations and analyses. The authors foreseen that this book has the potential to better expand the knowledge and share the experiences with those from the same field or to someone new to it.

Available in PDF, EPUB and Kindle. Book excerpt: The full potential of geophysics in engineering investigations is still to be realised. The many available techniques can provide important information about the ground, its mass properties, its small-scale variations, and its anomalies of structure or content. The advantage of a geophysical survey is that it enables information to be obtained for large volumes of ground that cannot be investigated by direct methods due to cost. The applications of geophysics in the characterisation of contaminated land are still developing, but have great potential for example in the distribution and migration of pollutants in the ground and groundwater. Geophysics is still insufficiently or inappropriately used in engineering and the newer capabilities are not appreciated, so there is a need for up-to-date guidance about how to apply geophysical investigations.This report is published in co-operation with the Geological Society and presents a logical guide through the process of using geophysical investigation methods in site characterisation. It explores the roles of geophysical methods and provides the background to geophysics as an investigative tool. The procurement, management and reporting frameworks for a geophysical investigation are set out, and the importance of the involvement of a recognised geophysics specialist adviser with the work is emphasised. The report explains the need for a conceptual ground model to enable appropriate investigative methods to be chosen. The underlying science and current practices of the main techniques are explained as well as the processes of data acquisition, handling and presentation. The different targets determinable by geophysical methods are considered in separate sections for geological, geotechnical, geo-environmental and structural engineering applications. The report concludes with recommendations for practice. The guide is aimed at geotechnical and civil engineers, geologists and engineering geologists, specialist geophysics contractors, contractors, consultants and clients.

This book was released on 2022 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electric resistivity imaging (ERI) is an effective non-destructive and rapid measuring way of obtaining continuous soil subsurface resistivity profiles. An ERI technique can be used to identify moisture variations and soil heterogeneities in an area. Thus, ERI is becoming a popular tool in geotechnical (FHWA, 2015)engineering; however, it only provides qualitative information at the current time. Using qualitative images, it is challenging to extract quantitative geotechnical information, such as the type of soil, moisture content, degree of saturation, and atterberg limit, of the subsurface. Several studies have described the electrical resistance of soil as a function of pore fluid conductivity and surface conductance. Additionally, electrical resistivity measurements have also been made on commercial soils in order to determine the influence of geotechnical properties. Since a conventional geotechnical investigation may not perform characterization tests of porewater or surface charge, electrical resistivity must be correlated with geotechnical properties that can be tested in the laboratory. The objective of this experimental study is to investigate the relationship between the electrical properties of soil and geotechnical parameters of locally available soil and determine correlations between geotechnical parameters and electrical resistivity that can be used by geotechnical engineers. A study was conducted to study the electrical properties of soils obtained from 22 boreholesof four different locations, namely Fort-Worth, Beaumont, Corpus Christi, and El-Paso, selected based on their geological formation. Besides collecting soil samples through soil borings using the Texas Cone Penetration (TCP) method, a field, electrical resistivity survey was also conducted using 28 and 56 electrodes at the same locations to obtain a subsurface resistivity map. Field resistivity values were correlated with soil TCP values, and the correlation was compared to previous literature. In this study, 44 soil samples classified as low plastic clay (CL), 15 samples as high plastic clay (CH), and four samples as elastic silt (MH) were used to measure the resistivity of compacted clay soils. Furthermore, soil samples were categorized into six categories based on their liquid limit higher than 50, between 35 and 50, and lower than 35, and plastic limit higher than 25 and lower than 25 to investigate the changes in geoelectrical properties of soil. Various geotechnical conditions were used in laboratory tests to determine the influence of soil parameters on electrical resistivity. In both clayey soils and sandy soils, electrical resistivity measurements were found strongly influenced by the moisture content and degree of saturation. Soil resistivity was found to be averagely decreased by 80%, 43%, and 21% of initial value when the soil moisture content was increased from 10% to 20%, 20% to 30%, and 30% to 40% except for the soil samples contains liquid limit less than 50 and plasticity index higher than 25 for unit weight of 11.8 KN/m3.Soil resistivity was found to be decreased by 42%, 25%, and 41% for the above-mentioned water content due to the high activity of soil. Moreover, soil resistivity decreases 45% and 49% of the initial values when the unit weight increases from 11.8 KN/m3 to 13.4 KN/m3 and 13.4 KN/m3 to14.9 KN/m3. Soil resistivity decreases as much as 57-fold for normal clay and 7.5 fold for active clay from the initial value when the degree of saturation increased from 17% to 100%. However, the rate of change of resistivity is low when the degree of saturation of compacted clay is more than 50%. Furthermore, clay properties such as liquid limit and plasticity index also affect electrical resistance at different saturation levels. However, at a higher level of saturation, geotechnical parameters have less impact on electrical resistivity. The soil engineering properties of both sandy and clayey soils were correlated with electrical resistance using different multiple linear regression (MLR) models developed with R-studio. In developing a multiple linear regression equation for clayey soil, the degree of saturation and plasticity index were selected as independent parameters, while for sandy soil, moisture and sand content were used. Validation of the MLR models was based on field data, and therefore these models can be used for estimating engineering properties.
