This book was released on 2004 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the evaluation of the capability of the current piezocone penetration test (PCPT) interpretation methods to reasonably predict the consolidation parameters needed to predict the total and time rate of settlement of cohesive soils. Seven sites in Louisiana were selected for this study. In each site, in-situ PCPT tests were performed and soundings of cone tip resistance, sleeve friction and pore pressures were recorded. Dissipation tests were also conducted at different penetration depths. High quality shelby tube samples were collected close to the PCPT tests and used to carry out a comprehensive laboratory testing program including unconfined compression test, triaxial test and one-dimensional oedometer consolidation test. The tangent constrained modulus, overconsolidation ratio and the vertical coefficient of consolidation, predicted using the different interpretation methods, were compared with the reference values determined from the laboratory consolidation tests.

Download or read book Normalization and Prediction of Geotechnical Properties Using the Cone Penetrometer Test CPT written by Richard Scott Olsen and published by . This book was released on 1994 with total page 644 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research was to develop techniques for (1) stress normalization of CPT measurements (and geotechnical properties) and (2) CPT prediction of geotechnical properties using cone and sleeve friction resistance values. Stress normalization allows a variable geotechnical property to be reduced to an equivalent value at a standard confining stress. A new concept, the Stress Focus, was identified which provides a basis for understanding soil strength as a function of confining stress. This study demonstrated that sand friction angles for different initial relative densities converge to a Stress Focus at high confining stress (approximately 100 atm), where the strength behavior is similar to that of a sedimentary rock. Dilation of dense sands decreases with increased confining stress until the Stress Focus is reached, as confirmed using historic high pressure triaxial test data as well with CPT measurements from laboratory chamber tests and uniform soil layers. The paths of convergence to the Stress Focus are exponentially related to confining stress and are the basis for development of CPT cone and sleeve friction resistance normalization techniques. The overburden stress at the Stress Focus is soil type dependent. The stress exponent for SPT normalization was shown to be equal to the CPT derived stress exponent. CPT correlations to geotechnical properties were established using both CPT cone resistance and friction ratio.

This book was released on 2015-12-11 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a one-stop reference to the empirical correlations used extensively in geotechnical engineering. Empirical correlations play a key role in geotechnical engineering designs and analysis. Laboratory and in situ testing of soils can add significant cost to a civil engineering project. By using appropriate empirical correlations, it is possible to derive many design parameters, thus limiting our reliance on these soil tests. The authors have decades of experience in geotechnical engineering, as professional engineers or researchers. The objective of this book is to present a critical evaluation of a wide range of empirical correlations reported in the literature, along with typical values of soil parameters, in the light of their experience and knowledge. This book will be a one-stop-shop for the practising professionals, geotechnical researchers and academics looking for specific correlations for estimating certain geotechnical parameters. The empirical correlations in the forms of equations and charts and typical values are collated from extensive literature review, and from the authors' database.

Available in PDF, EPUB and Kindle. Book excerpt: The Penetrometer and Soil Exploration: Interpretation of Penetration Diagrams—Theory presents the many uses of the penetrometer for investigating soil conditions. Testing methods include the following: (1) in situ load tests on full-scale foundations; (2) laboratory testing of undisturbed samples, and (3) in situ testing of soils. The book regards the advantages of using the penetrometer as a handy tool in drilling and sampling. The text emphasizes that the investigator should never rely entirely on the analogy or the extrapolation of information pertaining to a nearby site. The text describes the different shapes of the penetrometer diagrams obtained from tests in homogeneous cohesionless soil, as well as the significance of the embedment of a pile into the bearing stratum for deep foundation designs. The paper discusses the De Beer theory, Kerisel's theory, and the theory developed at the Delft Laboratory of Soil Mechanics. The laboratory determines the maximum soil pressure and the corresponding embedment of the pile. According to Professor L'Herminier, "the bearing capacity of a pile may be determined...from laboratory tests on soil samples, the other by extrapolating penetrometer data." The book is suitable for structural engineers, civil engineers, geologists, architects, and students of soil mechanics.

Available in PDF, EPUB and Kindle. Book excerpt: This research uses theoretical analyses to investigate the fundamental mechanisms controlling the performance of common in-situ penetration tests which are used to estimate the engineering properties of cohesive soils. The mechanics of penetration processes are modelled using the Strain Path Method together with generalized effective stress soil models. The analytical predictions provide a rational basis for establishing how soil properties are related to in-situ measurements. The predictions are evaluated by comparison with field data from well documented test sites. Results of this research show the following: (1) The cone resistance and excess pore pressures measured on the face of the cone during piezocone penetration are the most reliable measurements for estimating changes in undrained shear strength within a given clay deposit. (2) There is no rational basis for correlations between dilatometer contact pressures and in situ K sub O stresses, undrained shear strength or preconsolidation pressure. (3) Model predictions provide a reliable basis for estimating the horizontal coefficient of permeability for normally and lightly overconsolidated clays (OCR

This book was released on 2019-05-31 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The purpose of this research project was to evaluate techniques to improve the application of in situ penetration testing to Florida soils, with emphasis on the electronic cone penetrometer test (ECPT). Topics addressed included describing the spatial variability of soil properties, classifying Florida soils with the ECPT, and correlating the ECPT with the standard penetration test (SPT). A collateral purpose was to create an in situ test data base consisting of 97 ECPT soundings and 79 SPT tests. This data base was subsequently evaluated using statistical analysis. The spatial variability study was carried out to evaluate methods of interpolation between test soundings. The techniques studied included three deterministic approaches (the mean, median, and a 10% trimmed average), three distance-weighting methods (two based on reciprocal distances, and linear interpolation), a random field model (a hybrid distance-weighting/regression model), and regression analysis. While none of the approaches stood out as consistently superior predictors, the deterministic approaches were generally inferior to the other, more sophisticated methods. The distance-weighting methods and the random field model performed comparably, but were sensitive to individual test soundings. The regression models predicted slightly better on the average, and with more stability. The ECPT classification study used parametric and nonparametric discriminant analysis of cone data on soils that had been identified from the SPT test. The ECPT was able to group soil accurately into one of seven categories (organics, clay, silt, clayey sand, silty sand, sand, weathered rock) approximately 40% of the time. This percentage increased to 70% when the three sand categories were combined, reflecting the SPT drillers' difficulties in discriminating silty soils. In the SPT-ECPT correlation study, average q^/N ratios for Florida soils were much higher than expected, possibly due to cementation or liquefaction. Regression analysis of the data suggested that the nature of the SPT-ECPT relationship is more a function of the magnitude of the tip resistance, and less of the actual soil type.
