This book was released on 1971 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: The conditions leading to the initiation of failure in slopes of overconsolidated clay or clay shale are investigated by means of two finite element programs. The analysis is two-dimensional and assumes plane strain in a homogeneous semi-infinite mass. The material is assumed to be linearly elastic and isotropic with body forces. No pore pressure effects are analyzed. The effects of initial stress ratio, slope angle, and available friction, are investigated for two smooth bottom models and the one rough bottom model. The results are presented in a dimensionless ratio involving the cohesion required to prevent the beginning of failure and the overburden stress at the toe before excavation.

This book was released on 2018 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geotechnical engineers deal with some challenging problems when encountering long-term slope stability in overconsolidated clays and clayey shales. One of these problems is determining a suitable method to estimate the reliable shear strength of overconsolidated clayey soils for long-term slope stability. According to Eversol (2013), one half of the counties in Nebraska have experienced slope failure in overconsolidated soils, especially in north and east Nebraska. In this research, shear strength characteristics of overconsolidated clayey soils of Nebraska is investigated in regard to long-term stability of slopes, and the failure mechanism in such soils is examined. Undisturbed samples from boring logs from two different failure locations were taken. The research involved laboratory testing to compare and investigate the shear strength parameters of overconsolidated soils in undrained and drained conditions at high and low normal effective stress levels. Some issues that are addressed include: (i) the shear strength reduction due to low effective stress in adrained condition, (ii) the swelling behavior during consolidation and shearing stages of saturated overconsolidated soils in low effective confining stress, (iii) the suitable shear strength that helps to design/repair slopes in overconsolidated soils of Nebraska. One major finding of this research is that one of the main reasons for slope instability in overconsolidated clayey soils and shales in Nebraska is shear strength reduction. This strength reduction, which usually causes a progressive failure in overconsolidated soils in Nebraska, is due to swelling and softening; (2) the presence of expansive clay minerals in overconsolidated soils induced additional swelling in some areas reduces the shear strength of soils dramatically, especially at shallow depths; and (3) the laboratory results showed that the fully softened shear strength from a consolidated drained triaxial test may present a suitable shear strength for long-term slope stability in overconsolidated soils in Nebraska.

Download or read book Weathering as a Predisposing Factor to Slope Movements written by Domenico Calcaterra and published by Geological Society of London. This book was released on 2010 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is intended to provide an up-to-date overview of the approaches, methodologies and techniques devoted to better understand-ing of the weathering conditions of rock masses on slopes. According to the local conditions, a variety of slope movements may take place and involve weathered rock masses. Shallow and rapid soil slips evolving to debris flows are probably the most common type of slope movement. At the same time, deep-seated, intermittent landslides can also affect large volumes of weathered rocks and soils. Despite the high frequency of landslides in weathered materials, and the damage and casualties they repeatedly cause, little is known about the relationship between weathering and slope move-ments. This book presents worldwide case studies, where a variety of geo-logical and geomorphological settings are discussed. The content is divided into three sections: the first is devoted to broad aspects of the weathering/landslide processes; the second and third sections include papers dealing with igneous/metamorphic and sedimentary weathered rocks, respec-tively.
