The test on the single pile was modeled using the computer program LPILE Plus version 4.0 (Reese et al., 2000). The soil profile was calibrated by alternating the input soil parameters until the curves matched between the measured and the calculated results. The new soil profile was then used to model the test on the pile group using GROUP version 4.0 (Reese and Wang, 1996). A match was made between the measured test results and those calculated using GROUP by defining p-multipliers for each of the rows. For Cycle 1 the p-multipliers were found to be 1.0, .55, and .5 for Row 1 through Row 3 respectively. For Cycle 10 the p-multipliers were found to be the same as those for Cycle 1.

The load resisted by the single pile was greater than the average load resisted by each pile in the pile group. While the loads resisted by the first row of piles (i.e. the only row deflected away from all other rows of piles) were approximately equal to that resisted by the single pile, following rows resisted increasingly less load up through the fourth row. The fifth row consistently resisted more than the fourth row. The pile group in sand resisted much higher loads than did the pile group in clay.

In order to analyze foundations supported by groups of vertical, pin-headed, laterally loaded piles, it is necessary to include in some rational way the effect of pile-soil-pile interaction, or the increase in pile-head flexibility that occurs in each pile in a group in comparison with an isolated pile. A study was undertaken to measure experimentally pile-head flexibility reduction (interaction) factors in a full-scale pile group in sand. The measurements were accomplished by testing individual piles within a pile group of nine piles cyclically at varying magnitudes of applied ground line shear, two-pile subgroups and three-pile subgroups. The response of certain unloaded piles was also monitored during these individual-pile and small-group tests. Analysis of the results indicated a significant effect of position on flexibility reduction in a two-pile group (leading or trailing) for piles spaced 3 diameters on center and loaded in line and a lesser effect for piles loaded side-by-side. A consistent set of interaction factors was developed from the experiments and applied to the analysis of deflection and shear load distribution in the full nine-pile group, which had been tested earlier on the same test site, through the use of simple matrix techniques.

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.

Damping ratios ranged from 23 to 50 percent for the 15-pile group and 29 to 49 percent for the 9-pile group. Both pile groups increased in damping as the deflections increased. The optimized mass in motion for the entire system was found to be roughly 21,000kg for the 15-pile group and 14,000 kg for the 9-pile group. Stiffness for the 15-pile group started at 50kN/mm and ended at 21kN/mm. The 9-pile group ranged from 28kN/mm to 12kN/mm.

Guiding the professional through the complexities of lateral-load design, this book and CD-ROM combination introduces the procedures involved in piles and pile group design. This is a problem that can only be solved by accounting for the soil resistance as related to the lateral deflection of the pile. Intricate equations are derived and fully explained, enabling the designer to find the critical loads, either causing a pile to be overloaded or causing too much lateral deflection. The CD-ROM contains simplified versions of two required programs that allow the reader to check the solutions of some of the examples given in the book and to find answers to related problems.
