This investigation was undertaken to determine the effect of saturation of dense sand on the response of square footings to nuclear blast-type loading. Tests were conducted with footings on the surface and at a depth of burial equal to the footing width with a water table coincident with the plane of the footing. The results of these tests were compared with data from similar tests on dry sand from a preceding study. Saturation of dense sand had the effect of reducing maximum displacement. The displacements of surface footings were only about 30 percent of the displacement of footings on dry sand with equivalent soil density and loading condition, and the displacement of shallow buried footings was reduced by 50 percent. Empirical load-displacement curves developed from previous studies on dry sand were shown to be conservative when used to predict the response of footings on saturated dense sand. The primary difference in response occurred after peak reaction. The footings on saturated dense sand came to rest immediately, while footings on dry sand continued to displace for some short distance. This behavior was attributed to the development of transient negative pore pressures resulting from dilation of the sand. A similar laboratory investigation on a medium-density sand is recommended in order to determine whether or not any tendency toward liquefaction may occur at the lower end of the range of densities of interest for protective structure foundations.

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.

The report describes the static and dynamic loading of a 12-inch-wide by 18-inch-deep by 6-foot-long rigid footing, representing the strip footing of a subsurface shelter. Boundary conditions simulated those of a torsionally restrained footing of a flexible arch structure with simulated overburden of 20 feet at one side of the footing. Saturated and partially saturated sand was the test soil. Several soil void ratios were employed, and the effect on the relationship between load and displacement of the footing caused by soil saturation at void ratios higher than the critical void ratio was desmonstrated.

This book gathers selected proceedings of the annual conference of the Indian Geotechnical Society, and covers various aspects of soil dynamics and earthquake geotechnical engineering. The book includes a wide range of studies on seismic response of dams, foundation-soil systems, natural and man-made slopes, reinforced-earth walls, base isolation systems and so on, especially focusing on the soil dynamics and case studies from the Indian subcontinent. The book also includes chapters addressing related issues such as landslide risk assessments, liquefaction mitigation, dynamic analysis of mechanized tunneling, and advanced seismic soil-structure-interaction analysis. Given its breadth of coverage, the book offers a useful guide for researchers and practicing civil engineers alike.
