Download or read book Sustainable Slope Stabilisation using Recycled Plastic Pins written by Sahadat Hossain and published by CRC Press. This book was released on 2017-06-14 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Landslides and slope failure are common in the US and rest of the world. The landslides cause significant damage to infrastructure and millions of dollars are required each year to fix the slope. A sustainable and costeffective option to stabilise the slope can have significant benefits, as it will reduce the cost of maintenance and when using recycled pins, it may help the environment at the same time. The recycled plastic pin is made from recycled plastic bottles and other plastic waste. Several demonstration projects already proved the effectiveness of RPP as an alternative option to fix slope failure, with a maximum failure depth of 7-8 ft. In this book, every detail of the slope stabilisation technique using recycled plastic pins, including the design techniques and several case studies, are included. This will help to explain the basics of this important technique and will be used as reference to design the slope stabilisation scheme using recycled plastic pins.

Download or read book Correlations for Fully Softened Shear Strength Parameters written by B. A. Castellanos and published by . This book was released on 2016 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fully softened shear strength is an important engineering concept for slope stability analyses of cuts in stiff clays and compacted embankments constructed of high plasticity clays. The "softening" concept has been used to explain many first-time failures for which the back-calculated shear strength is below the peak strength measured in the laboratory using undisturbed or freshly compacted samples. A comprehensive laboratory testing program was undertaken to measure the fully softened shear strength of 46 soils using over 300 direct shear tests. These results were used to develop correlations that allow estimation of a continuous and nonlinear fully softened failure envelope using soil index properties. These new correlations were developed to address some of the problems observed with existing correlations for fully softened shear strength parameters. The new correlations are presented along with the statistical parameters needed to assess reliability of the shear strength parameters and to allow use within a probabilistic framework.

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.

Available in PDF, EPUB and Kindle. Book excerpt: An investigation has been conducted to gain a better understanding of the drained residual and fully softened shear strengths of cohesive soils, the shear strength mobilized in field case histories involving previous and no previous sliding in stiff clays, and develop empirical relationships that describe the stress-dependent nature of the residual and fully softened shear strengths in terms of soil index properties. To investigate the drained residual strength, a Bromhead ring shear apparatus was modified to allow testing of overconsolidated, presheared, remolded soil specimens of different plasticity and clay-size fraction. Residual shear strengths measured using the modified ring shear apparatus were compared to shear strengths measured in conventional reversal direct shear tests on precut remolded specimens and shear strength values back-calculated from well documented field case histories of slopes that underwent previous sliding. The modified ring shear, direct shear, and triaxial compression apparatuses were used to investigate the fully softened shear strength using normally consolidated, remolded specimens. The natural soils used in the residual and fully softened research have a range of liquid limit of 24 to 286%, plasticity index of 8 to 244%, and clay-size fraction of 10 to 88%. New relationships describing the residual and fully softened friction angles developed from the extensive ring shear testing were presented in terms of the liquid limit, clay-size fraction, and effective normal stress. Most of the existing residual and fully softened strengths relationships are based on only one soil index property and provide a friction angle that is independent of effective normal stress. The importance of incorporating the liquid limit, clay-size fraction, and effective normal stress in estimating the residual and fully softened friction angles was illustrated using field case histories. Several first-time slides through stiff fissured clays were also studied to estimate the shear strength mobilized during failure. Based on these studies and laboratory test results, recommendations for estimating the field shear strength of stiff fissured clay involved in first-time slides were presented. A reanalysis of the 1981 upstream slide in San Luis Dam was conducted to evaluate the shear strength reduction caused by the displacement induced by repeated loading. The effect of plasticity and degree of overconsolidation on this shear strength reduction was investigated.

Available in PDF, EPUB and Kindle. Book excerpt: The fully softened strength (FSS) is usually the controlling shear strength for cut slopes in stiff-fissured fine-grained soils, shales, and claystones, engineered fill slopes, and compacted embankments with no prior slope movement. The FSS is used to model the shear strength of shallow slope soils because it represents the shear strength remaining after the effects of overconsolidation, compaction, desiccation, or other strengthening processes have been removed because of wet-dry cycles, applied shear stresses, stress relief, progressive deformation or failure, swelling, freeze-thaw cycles, weathering, or all of these. An empirical correlation is frequently desired for such slopes because the slopes can be long, such as a levee system, and the borrow material is not completely defined, which makes comprehensive testing difficult. This article presents the mode of shear for the FSS condition, a comparison of existing FSS correlations, power function coefficients to estimate the FSS envelope, and recommendations for modeling the stress-dependent FSS envelope in stability analyses.
