Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for Information and Numerical Data Analysis and Synthesis, (CINDAS) *at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity was transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 19 (thesis year 1974) a total of 10,045 theses titles from 20 Canadian and 209 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. The organization of Volume 19 is identical to that of past years. It consists of theses titles arranged by discipline and by university within each discipline.
A laboratory study was conducted to investigate the effect of cementation on the cone penetration resistance of sand. A new apparatus to form homogeneous artificially cemented sand specimens as well as uncemented ones, and a miniature quasi-static cone penetrometer were developed. Artificially cemented specimens with 1 and 2% cement content and relative densities ranging from 18 to 80% were tested. The penetration resistance of the cemented specimens was compared with those of comparable uncemented specimens. The influence of cement content and relative density of the specimens on their quasi-static cone penetration resistance was studied. The results indicate that cementation has a pronounced effect on the penetration resistance of sand.
A standard method to determine the liquefaction resistance of clean sands over a range of depths based on in-situ cone penetration tests is to convert measured cone penetration resistances (q[subscript c]) to an equivalent cone penetration resistance expected at an overburden stress of one atmosphere (q[subscript c1]) using the overburden correction factor (C[subscript N]). The method assumes that cone penetration resistance is normalized to an equivalent cone penetration resistance at an overburden stress of one atmosphere for the same relative density or state parameter. Numerous methods have been developed to normalize cone penetration resistance based on a constant state parameter (state normalized penetration resistance) as a method for representing the effect of overburden stress on liquefaction resistance. Several of these methods yield considerably different results of state normalized penetration resistance. The goal of this research is to compare three methods used to determine state normalized cone penetration resistance at a reference stress of one atmosphere for four well studied clean sands. Cone penetration theory and empirical relations of the different frameworks are reviewed. Calibration chamber data of the four sands is corrected for calibration chamber effects by two differing methods, corrected for lateral earth pressure effects, and converted to state normalized tip resistance using the evaluated methods. The resulting normalized tip resistances from the three methods are compared and checked for bias. Two measures of state, namely the state parameter and the relative state parameter, are compared to state normalized tip resistances for the four sands to determine whether either parameter minimizes the dispersion in the relationships, with insufficient conclusions. The interdependence between the crushing behavior of clean sands, the limiting compression curve, and state normalized tip resistance is evaluated, suggesting a correlation between the limiting compression curve and state normalized tip resistance. Finally, the overall correlation between the state or relative state parameter and the state normalized tip resistance is evaluated based on the data for the four sands. Two general correlations are shown corresponding to the two differing calibration chamber corrections, illustrating the expected scatter of estimated state for a clean sand. A background and review of the general correlations are provided.
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.
Sponsored by the Executive Committee of the Geotechnical Engineering Division of ASCE. This Geotechnical Special Publication contains eight lectures given between 1974 and 1983 in honor of Karl Terzaghi and repressenting diverse aspects of geotechnical engineering and engineering geology. Topics include: the relationship of geology and geotechnical engineering and how a study of the geology of engineering sites is an important starting point for all geotechnical site studies; effects of dynamic soil properties on soil-structure interaction; bearing capacity and settlement of pile foundations; design and construction of drilled shafts; evaluating calculated risk in geotechnical engineering; proposal forØthe establishment of a national center for investigating civil engineering failures, with several case studies; pre-Columbian earth construction in the Americas and technological developments between 2,500 and 500 years ago; and recent progress in the design and construction of concrete-face rockfill dams. The 1978 lecture by the late N.M. Newmark is not included.
