CASE STUDY Project Summary ® ™ Organization SVSLOPE and SVFLUX Applied to Slope Deep Foundations Institute Solution Geotechnical Engineering Stability Analysis for International Institute Project Objectives DFI Used Bentley’s SoilVision Applications for Summary of Factor Safety Numbers • To conduct a 2D/3D slope stability analysis as part of a modeling challenge. Deep Foundations Institute (DFI) is an international By using these applications, DFI received summary • To obtain a minimum geotechnical association of contractors, engineers, manufacturers, of factor safety numbers of 2D and 3D slope factor of safety and associated suppliers, academics, and owners in the deep potential failure surface results. stability models for clay and silt material types, foundation industry. Their mission is to bring both drained and undrained. The organization Products Used together multidiscipline individuals and organizations SVSLOPE®, SVFLUX™ also realized that 2D or 3D analysis can be to find common ground and create a shared vision performed in LEM or seepage analysis and that for continual advancement in the deep foundations it can consider unsaturated material properties, Find out about Bentley industry. With more than 3,300 members worldwide, anchor supports, grouted tiebacks, micropiles, DFI recently used Bentley’s SVSLOPE and SVFLUX geomembranes, and rockpiles when analyzing. at: www.bentley.com software to carry out a 2D/3D limit equilibrium slope The LEM analysis was quick and simple to set Contact Bentley stability analysis as part of a modeling challenge. 1-800-BENTLEY (1-800-236-8539) up using these applications, as well as setting Outside the US +1 610-458-5000 The organization wanted to create a model, model geometry, and materials, specifying the analysis up the material parameters. SVFLUX allowed DFI Global Office Listings settings. Then, the project team created, defined, to incorporate a coupled seepage analysis to better www.bentley.com/contact and assigned several parameters, including the consider the drains. Moving forward, DFI would water-table and piezometric line, distributed loads, like to examine the influence of 3D drainage and supports. Finally, the team analyzed the models configurations, 3D effects on groups of piles, cost to obtain a minimum geotechnical factor of safety analysis of different solutions, and the potential and associated potential failure surface results. influence of non-ellipsoidal 3D slip surfaces. Stability analysis for berm added Stability analysis for drain, micropiles, and anchors Stability analysis for concrete buttress © 2019 Bentley Systems, Incorporated.
