Download or read book Modified Ohio s Curves written by Suksun Horpibulsuk and published by . This book was released on 2009 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compaction curves from 16 coarse- and 9 fine-grained soils, which cover all soil types classified by the Unified Soil Classification System are analyzed to develop the Modified Ohio's curves. For all soils, the relationships between water content and degree of saturation on both the dry and the wet sides of optimum are represented by power functions. Their compaction curves under standard Proctor energy follow the Ohio's curves. Optimum degree of saturation, ODS, of coarse-grained soils is lower than that of fine-grained soils. However, for a given soil, the ODS is practically the same for different compaction energies, E. Even though compaction characteristics (optimum water content, OWC, and maximum dry unit weight, ?d max) are different for different soils, their relationship between normalized OWC/OWCst and E is practically the same, where OWCst is the OWC at standard Proctor energy. Based on this finding, the Modified Ohio's curves are introduced under compaction energy levels of the half standard, half modified, and modified Proctor energies. The verification of the Modified Ohio's curve is also illustrated in this paper. These curves are useful in rapid estimation of laboratory compaction curves from a single set data of dry unit weight and water content.

Download or read book Influence of Compaction Energy on Soil Engineering Properties written by Isaac Robert Drew and published by . This book was released on 2005 with total page 722 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strength and deformation parameters of compacted soil are known to be related to soil type and moisture content. However, little attention has been directed towards understanding the influence of compaction energy on these properties. This paper describes laboratory and field studies conducted to evaluate the relationship between soil type, soil moisture content, and compaction energy on seven cohesive soil types. In the lab, specimens were compacted with impact energy at levels of 355, 592 (standard Proctor), 987, 1643, and 2693 kJ/m3 (modified Proctor) over a wide range of moisture contents to determine dry unit weight, unconfined compressive strength and the secant (50 percent strain) stiffness. In total, 175 Proctor tests and 95 unconfined compression tests were performed. At each energy level, a soil was tested at 4 to 5 moisture contents with respect to its standard Proctor moisture range. In addition, 54 consolidated undrained triaxial tests were performed at the five energies and four moisture contents for one soil to evaluate changes in effective stress shear strength parameters. This paper summarizes the results of statistical analyses performed on all lab and field tests conducted. The models that best explain variability in dry unit weight, strength, and stiffness are presented. Models are presented individually for each soil type and also inclusive of all soils grouped together. Independent variables used in the modeling include compaction energy, moisture content, confining pressure, Atterberg limits, material passing the No. 200 sieve, and clay fraction. In addition, a new compaction model, derived from a linear rate equation, is presented and checked for validity in estimating soil dry unit weight as a function of compaction energy. Results indicate that compaction energy, combined with moisture content, is a key factor in determining soil strength and stiffness parameters. It is concluded that the strength and stability of a compacted soil cannot be assessed in terms of relative compaction alone. Instead, this research encourages the use of strength and stiffness in the design and construction phases of earthwork operations, being the true functional requirements for compaction specifications.

Download or read book Correlations of Soil and Rock Properties in Geotechnical Engineering written by Jay Ameratunga and published by Springer. This book was released on 2015-12-11 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
