Available in PDF, EPUB and Kindle. Book excerpt: This study presents numerical and theoretical investigations on the bearing capacity of a single pile in sand under axisymmetrical loading conditions. An extensive literature review for the existing theories is presented. The published reports showed a wide range of discrepancies exists among previous theories developed to predict bearing capacity of a single pile in sand. A numerical pile load-testing program was carried out using finite element technique to cover a wide rang of pile geometry and sand states. Mohr-Coulomb criteria were used to model the sand behavior. Linear strain quadrilateral elements were employed to model soil and pile. A chain of slip elements was placed around the pile to model the slippage between sand and pile. The numerical model was validated against field load tests data. The numerical model was then used to analyze stresses influencing the pile behavior in sand and to establish the pile failure mechanism. The stresses and coefficient of earth pressure acting on the pile shaft were reported. A new failure mechanism was developed which varies with: pile geometry, coefficient of earth pressure, shaft roughness and angle of shearing resistance of sand. A theoretical model was developed to predict the ultimate bearing capacity of a single pile in sand, utilizing the proposed failure mechanism. A data analysis procedure was employed to develop the new model parameters predictive formulas. An approximate method to predict the coefficient of earth pressure acting on the pile shaft was developed and used extensively in the theoretical model. A sensitivity analysis was conducted on the varying parameters of the theoretical model. The theoretical model incorporates salient features previously omitted in conventional bearing capacity theories: treating the bearing capacity of a single pile in sand under axisymmetrical conditions, adopting the punching shear failure as a principle failure mode, and accounting for the interdependence between skin friction and tip resistances. The theoretical model showed that the average unit skin and tip resistances increase, but at a lower rate below the critical depth. These findings concur with the recent research conclusions, which indicate that the average skin resistance tends to increase with depth. A computer program "G-Pile" was developed to facilitate the massive mathematical calculations of the theoretical model. The computer program "G-Pile" was used to produce data for charts of the factors needed to predict the bearing capacity of a single pile in sand. A design procedure is proposed and verified against field test results, good agreement was achieved. Recommendations are given for future research.
Book Synopsis Analytical Methods in Petroleum Upstream Applications by : Cesar Ovalles
Download or read book Analytical Methods in Petroleum Upstream Applications written by Cesar Ovalles and published by CRC Press. This book was released on 2015-04-02 with total page 2054 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effective measurement of the composition and properties of petroleum is essential for its exploration, production, and refining; however, new technologies and methodologies are not adequately documented in much of the current literature. Analytical Methods in Petroleum Upstream Applications explores advances in the analytical methods and instrumentation that allow more accurate determination of the components, classes of compounds, properties, and features of petroleum and its fractions. Recognized experts explore a host of topics, including: A petroleum molecular composition continuity model as a context for other analytical measurements A modern modular sampling system for use in the lab or the process area to collect and control samples for subsequent analysis The importance of oil-in-water measurements and monitoring The chemical and physical properties of heavy oils, their fractions, and products from their upgrading Analytical measurements using gas chromatography and nuclear magnetic resonance (NMR) applications Asphaltene and heavy ends analysis Chemometrics and modeling approaches for understanding petroleum composition and properties to improve upstream, midstream, and downstream operations Due to the renaissance of gas and oil production in North America, interest has grown in analytical methods for a wide range of applications. The understanding provided in this text is designed to help chemists, geologists, and chemical and petroleum engineers make more accurate estimates of the crude value to specific refinery configurations, providing insight into optimum development and extraction schemes.

Vanapalli and published by . This book was released on 2018 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental studies were undertaken to investigate the vertical load versus displacement behavior of single model piles in sand (i.e., Unimin 7030 sand) under both saturated and unsaturated conditions. Stainless steel model piles with three different diameters (i.e., 19.25, 31.75, and 38.3 mm) with a length of 350 mm were used to conduct the pile load tests. Semiempirical methods were proposed to successfully predict the variation of end- and shaft-bearing capacities of single piles with respect to matric suction by modifying three conventional end-bearing capacity equations (Terzaghi 1943; Hansen 1970; Janbu 1976) and the ?-method (Burland 1973), respectively. In addition, finite element analyses were also carried out to simulate vertical load versus settlement behaviors of model pile tests using a commercial finite element software, SIGMA/W (GeoStudio 2007).
