Available in PDF, EPUB and Kindle. Book excerpt: The Hunter Creek sandstone near Mogul, Nevada, is a Neogene sedimentary unit in the Verdi basin consisting of fluvial, deltaic, and lacustrine facies. Numerous slope failures have occurred in the unit mostly along streams, canals, and the Truckee River. Field mapping showed that most of the slope failures occur south of Interstate 80 between Verdi and northwest Reno, Nevada. Four landslides were studied and analyzed south of I-80. Field work included failure mapping, obtaining bedding orientations, and sample collection for laboratory testing. A monument was placed in an active failing mass to track movement over the spring of 2012 annual snow-melt. Laboratory testing included particle size distribution, specific gravity, Atterberg limits, and direct shear testing. An engineering stratigraphic column was created comparing particle size with friction angle and the plasticity of the soils. The four slope failures were modeled using the computer program SLIDE. Each slope was modeled to represent spring thaw conditions with a high groundwater level and an analysis was performed on each slope to determine the sensitivity of the factor of safety with drops in water levels. Two failure criteria were used in modeling: the Coulomb failure criterion and the Hoek-Brown failure criterion. The analyses confirmed that the slopes in these units are close to failure (FS > 1.0) as a result of low friction values and cohesion. Residential development south of I-80 is likely to continue, so the slopes were modeled showing a cut and fill typical of areas developed on sloped terrain. Analyses confirmed that surcharges from regrading combined with high water level conditions would lead to slope failure. The study area is also seismically active and the cut and fill model was analyzed to determine stability problems during earthquakes.
Book Synopsis Slope Engineering for Mountain Roads by : Gareth J. Hearn
Download or read book Slope Engineering for Mountain Roads written by Gareth J. Hearn and published by Geological Society of London. This book was released on 2011 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Provides a complete guide to the study, design, construction and management of landslide and slope engineering measures for mountain roads, with emphasis on low-cost. The geographical focus is on the tropics and sub-tropics, but is also highly relevant to other regions where heavy rain, steep slopes and weak soils and rocks combine to create slope instability. The causes and mechanisms of landslides are described, and the hazards they pose to mountain roads are illustrated. Methods of desk study, field mapping and ground investigation are reviewed and illustrated, with emphasis on geomorphological and engineering geological techniques. The design and construction of alignments, earthworks, drainage, retaining structures, the stabilization of soil slopes and rock slopes, and the control of erosion on slopes and in streams covered. Slope management as part of road maintenance and operation is reviewed, and procedures for risk assessment and works prioritization are described.
Book Synopsis Susceptibility to Slope Failure and Development Suitability Near Highway 79 in the Hermosa NW and Hermosa Quadrangles, Pennington County by : Matthew David Minnick
Download or read book Susceptibility to Slope Failure and Development Suitability Near Highway 79 in the Hermosa NW and Hermosa Quadrangles, Pennington County written by Matthew David Minnick and published by . This book was released on 2008 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: A slope stability analysis was performed to create factor-of-safety maps to assess slope failure susceptibility in areas of future land development in the Hermosa NW and Hermosa 7.5 minute quadrangles in Pennington County. Funding was provided by the Penning County Commission in a partnership with the South Dakota School of Mines & Technology, and RESPEC. The slope stability analysis included an existing slide inventory, aerial mapping, soil core sampling, soils laboratory testing, limit equilibrium modeling, and geographic information system (GIS) spatial analysis. The existing slide inventory was required to assess current and past failure conditions in areas prone to slope failure. Digital orthoquad imagery, a low-level plane survey, and extensive field global positioning system (GPS) mapping were used to produce the slide inventory. Eight suitable sampling sites were selected on the basis of geologic formation, accessibility, and land ownership approval. Shelby tube samples were collected up to 25 feet deep at each sample location using a 4"auger on a truck-mounted drilling rig. Geotechnical laboratory tests were performed on soil cores in depth-specific increments yielding 24 analyses including unit weight, plasticity indices, and direct shear tests to acquire cohesion and friction angle values. Limit equilibrium models were built in slope stability analysis software using profiles gathered from field GPS mapping and United States Geological Survey 10-meter digital elevation model data. Models were run for unsaturated and saturated conditions. Factor-of-safety trend models were built to correlate geology and slope. Raster files of the slope angle and geology were created, reclassified, and added together, and correlated with the factor of safety trend models to generate factor of safety maps in GIS. Spatial model accuracy was verified using the existing slide inventory. Results indicated that the Cretaceous Graneros Group rocks were most susceptible to slope failure under current conditions, particularly the Skull Creek and Belle Fourche Shale formations. The Mowry Shale member and the Upper Cretaceous Carlile Formation were less prone to failure but became susceptible with added stresses. Results were used along with the geologic map aquifer susceptibility, surface water, and soil engineering properties data, to create a multivariate development suitability model, named the Black Hills Development Suitability Risk model, or BH-DSR model. The BH-DSR model is in use by the Pennington County Planning Commission to help them make informed decisions on the impact to development from natural hazards and the impact of development on the environment.

Book Synopsis 2016GUIDELINES FOR INVESTIGATING GEOLOGIC HAZARDS AND PREPARING ENGINEERING-GEOLOGY REPORTS, WITH A SUGGESTED APPROACH TO GEOLOGIC-HAZARD ORDINANCES IN UTAH by : Steve D. Bowman
Download or read book 2016GUIDELINES FOR INVESTIGATING GEOLOGIC HAZARDS AND PREPARING ENGINEERING-GEOLOGY REPORTS, WITH A SUGGESTED APPROACH TO GEOLOGIC-HAZARD ORDINANCES IN UTAH written by Steve D. Bowman and published by Utah Geological Survey. This book was released on 2016-09-21 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of these guidelines for investigating geologic hazards and preparing engineering-geology reports, is to provide recommendations for appropriate, minimum investigative techniques, standards, and report content to ensure adequate geologic site characterization and geologic-hazard investigations to protect public safety and facilitate risk reduction. Such investigations provide important information on site geologic conditions that may affect or be affected by development, as well as the type and severity of geologic hazards at a site, and recommend solutions to mitigate the effects and the cost of the hazards, both at the time of construction and over the life of the development. The accompanying suggested approach to geologic-hazard ordinances and school-site investigation guidelines are intended as an aid for land-use planning and regulation by local Utah jurisdictions and school districts, respectively. Geologic hazards that are not accounted for in project planning and design often result in additional unforeseen construction and/or future maintenance costs, and possible injury or death.
