Book excerpt: In this volume, soil creep is analysed within the framework of other soil-rheological phenomena, such as stress relaxation and long-term resistance, to present an in-depth discussion of the effect of time on soil behaviour. As time is the only state parameter which cannot be entirely modelled in the laboratory, the presented extrapolation is based upon a combination of appropriate theoretical analysis, and the principles of the physical behaviour of soils affected by state parameters such as porosity, water content, stress, strain, time and temperature. Principal macro- and microrheological theories are analysed, and a comprehensive picture of the soil structure and of the effect of state parameters is presented, documented by the author's experiments and illustrated by many examples. The theory of hereditary creep was selected as the best theory serving the author's purpose to propose simple constitutive relations governing creep of soils. The proposed constitutive relations have been implemented into FEM programs and the effect of the time factor has been demonstrated by the solution of such boundary value problems as a dams and underground tunnels. This volume should be of interest to civil engineers, scientists, research and postgraduate students, and advanced undergraduates.

This book was released on 2011-09-07 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doctoral Thesis / Dissertation from the year 2010 in the subject Engineering - Geotechnology, , course: Civil Engineering, language: English, abstract: With growing infrastructure developments in hilly areas and due to economical constraints of using locally available rockfill materials for construction of embankments, practicing engineers must be acquainted with geotechnical response of non-conventional granular soils. These materials are most likely to disintegrate with time due to physical and chemical weathering. In general, the laboratory investigations on durability characteristics of such materials are only made through simple slaking tests. However, studies examining the effects of slaking-induced disintegration of soil grains on the geotechnical engineering analysis and design parameters are rather limited. This is essentially due to the reason that the grains of standard laboratory sands are mostly durable and hence, the stress-strain response is considered to be unaffected by the presence of water. In order to explore the possible effects of deterioration of soil grains on static and dynamic properties of granular soils, a series of consolidated drained torsional shear tests on various crushed soft rocks were performed under saturated and dry conditions and compared with a well reported Toyoura silica sand consisting of durable grains. Due to the sensitivity of crushed rockfill to deteriorate upon water-submergence, test under dry conditions represented the response of a soil with intact grains, whereas a similar test under saturated condition simulated the potential reduction in strength and stiffness of the soil with time. From the grain size distributions determined after each test, a degradation index was defined to quantify the degree of disintegration of grains. Strength and deformation properties determined from monotonic as well as cyclic shear tests were then compared with this index. Possible correlations of water-induced deterioration of soil grains with consolidation behaviour, peak shear strengths, friction angles, dynamic shear stiffness, and volume-change characteristics during shearing were explored. In addition, the effects of confining stress and shear strain level on particle breakage were also investigated. It was concluded that time-dependent characterization of rockfill materials by monitoring the degree of deterioration can be helpful to avoid catastrophic geotechnical failures. Nonetheless, this study is a caution to conventional soil mechanics in which decay of grains and loss of soil strength with time are often uncared.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research is the development of a new constitutive model to describe the behavior of cohesive soils under time dependent loading. In the work presented here, the modified SIMPLE DSS model is expanded to account for the effects of strain rate on clays in simple shear conditions. The response of clay soils is highly dependent on the rate of strain for both effective stress path and stress-strain behavior. The undrained shear strength is strongly influenced by strain rate both in monotonic and cyclic simple shear tests. Nevertheless, the few available experimental results cover a very limited range of loading conditions and rates. The existing literature established that the soil response display a unique relationship between shear strength and log scale of strain rate. To include the effects of strain rate, the modified simple effective stress model starts with two assumptions: (1) a specific shear strength corresponds to a specific strain rate in a unique relation; and (2) the effect of strain rate does not change the failure envelope. The proposed model is developed from the original SIMPLE DSS model, based on an effective stress formulation in a reduced stress space, and utilizing concepts related to the framework of bounding surface plasticity. The proposed model evaluation was carried out comparing model simulations with results of simple shear tests on Boston Blue Clay and San Francisco Young Bay Mud. The model capability is useful especially in strain rate dependent responses for both monotonic and cyclic behavior, including irregular loading and step-changed condition. It was found that undrained shear strength in simple shear is directly related to strain rate effects and the responses in cyclic test show the more rate dependent behavior than those in monotonic test. The proposed model is able to predict the increase in undrained shear strength for higher strain rate.

Book excerpt: Soft soils present particular challenges to engineers and an understanding of the specific characteristics of these soils is indispensable. Laboratory techniques such as numerical modelling, theoretical analysis and constitutive modelling give new insights into soft soil material behaviour, while large-scale testing in the field provides important information in areas such as slope stability and soft soil improvements. This collection of papers from the Fourth International Conference on Soft Soil Engineering, Vancouver, 2006, presents an international appraisal of current research and new advances in engineering practices, illustrating the theory with relevant case studies. Geotechnical professionals, engineers, academics and researchers working in the areas of soft ground engineering and soft soil engineering will find this a valuable book.

Available in PDF, EPUB and Kindle. Book excerpt: In November 2015, Buenos Aires, Argentina became the location of several important events for geo-professionals, with the simultaneous holding of the 6th International Symposium on Deformation Characteristics of Geomaterials, the 15th Pan-American Conference on Soil Mechanics and Geotechnical Engineering (XV PCSMGE), the 8th South American Congress on Rock Mechanics (SCRM), as well as the 22nd Argentinean Congress of Geotechnical Engineering (CAMSIGXXII). This synergy provided a unique opportunity to exchange ideas and discuss current and future practices in the areas of soil mechanics and rock mechanics, and their applications in civil, energy, environmental, and mining engineering. This book presents the proceedings of the 6th International Symposium on Deformation Characteristics of Geomaterials. As well as 118 articles selected for publication after peer review, it includes 7 lectures delivered by invited keynote speakers and the Third Bishop Lecture, delivered by Professor Herve Di Benedetto of the University of Lyon, France, who presented a reference work on the advanced testing and modeling of bituminous bounded and unbounded granular materials. The conference brought together practitioners, researchers and educators from around the world engaged in the understanding of the deformation properties of geo-materials before failure, and the small strain parameters as fundamental characteristics of geo-materials. The main topics covered by the symposium include experimental investigations from very small strains to beyond failure, including multi-physical approach; HTC M coupling behavior, characterization and modeling of various geo-materials and interfaces; and practical prediction and interpretation of ground responses: field observation and case histories.
