Book Description
Results and analyses of a series of strain-controlled, consolidated-undrained and unconsolidated-undrained triaxial compression tests performed on various gradations of artificially blended earth-rock mixtures and on a natural earth-rock mixture associated with the construction of DeGray Dam, Caddo River, Arkansas, are presented. It was shown that R triaxial tests on scalped/replaced gradations of a soil-rock mixture may yield substantially overconservative estimates of the strength of the full-scale material depending on the gravel content and plasticity of the fine fraction. On the other hand, Q tests on scalped/replaced specimens may over-estimate the strength of the full-scale gradation. It is recommended that triaxial testing of earth-rock mixtures be performed on the full-scale material (large specimens) or at least on the altered gradation obtained by removing (scalping) no more than 10% by weight of the full-scale material's largest particles. While this investigation did not seek to determine the effects on strength-deformation behavior of earth-rock mixtures of plasticity of the fines. Test results suggest that plasticity of the fines influences the differences seen between strengths of full-scale material as compared to scalped/replaced material.

Book Description
The theme of the 31st US Symposium on Rock Mechanics is 'Rock Mechanics contributions and challenges', having as objective the examination and quantification of the progress that has been achieved in addressing the major practical challenges facing the science of rock mechanics and mine design. The 124 papers included in the proceedings cover areas such as: experimental studies (laboratory and field); conceptual, analytical, and numerical modeling; design and construction methods. 35 papers deal with practical mining problems and include information on rock reinforcement technology, blasting, rock bursts, open pit mining, remote sensing and borehole geophysics, mechanical fragmentation, and subsidence. Areas emphasized are coal and metal mine design problems. Other papers deal with the newest computer models, new instruments, fracture mechanics, new laboratory testing techniques, and in situ testing.

Book Description
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.

Book Description
"Although the triaxial compression test is presently the most widely used procedure for determining strength and stress-deformation properties of soils, there have been no books published on triaxial testing since the 1962 second edition of the landmark work The Measurement of Soil Properties in the Triaxial Test by Bishop and Henkel. It is apparent there is a need to document advances made in triaxial testing since publication of Bishop and Henkel's book and to examine the current state of the art in a forum devoted solely to triaxial testing. Because of increasing versatility brought about by recent developments in testing techniques and equipment, it is also important that the geotechnical profession be provided with an up-to-date awareness of potential uses for the triaxial test."--Overview.
