Success Stories

October 4, 2016

A tailings storage facility of a mine site in South America was analyzed using SVSLOPE®. With a maximum height of 50m, the facility was located in a mountainous region within a relatively narrow valley. The bottom of the valley consisted of soft clay deposits, while the side valley consisted primarily of coarse alluvial soil deposits. The embankment was founded directly on top of these soils deposits.

Three cross-sections, each one representing different foundation conditions along the embankment, were analyzed in SVSLOPE®2D to guarantee the physical stability of the facility. The cross-section that included the soft soils materials yielded the lowest 2D factor of safety through a deep rotational failure surface; the design of the facility was developed based on this finding. However, it was clear that the deep failure surface defined as a critical was a function of the soft clayey soil which did not take into account the 3D effects generated by the surrounding coarse alluvial materials.

To evaluate the 3D-effects induced by the foundation soils and the narrow valley on the physical stability of the tailings storage facility, a 3D slope stability analysis was conducted using SVSLOPE®3D. The three existing cross-section were rapidly interpolated to generate a 3D model: both the materials and groundwater level transitioned from 2D to 3D conditions. The 3D analysis resulted in a more shallow failure surface and higher factor of safety due to the influence of the coarse granular materials located on the side of the valleys. Further raises of the embankment will take into account these findings and will most likely include 3D analyses. SVSLOPE® proved to be a user-friendly and efficient tool to transition from 2D to 3D analysis using cross-sections as input.

Testimonials

  • "We have allowed our students the choice of using multiple Geotechnical software suites in our Dam Design and other Geotechnical courses. Our students consistently gravitate towards SoilVision software as being the most modern and user-friendly."

  • "I've been a geotechnical engineer for more than 25 years and SoilVision has the best tech support I have ever worked with. I truly appreciate their patience and help over the past year."

  • "Peter Brett Associates have been looking to update our existing slope stability software over the last year. After extensive research and trials, SVSLOPE® developed by SoilVision Systems Ltd. was found to meet all our existing and future design requirements. Its ease of use for modeling simple as well as complex geological and geometrical problems was a critical factor in our assessment as well as the incorporation of design to the Eurocodes. Their customer support has been faultless and their willingness to develop the software to meet our own specific design requirements is a most gratifying added bonus."

    "We love the fact that SVSLOPE® is part of an integrated suite of software and that, if required, 3D analysis can be undertaken. We would recommend this product to other geotechnical consulting firms."

  • "We have been using SVSLOPE® and SVFLUX™ for the past year and have found them to be efficient and productive engineering tools which have allowed us to offer our services in an efficient manner. The capability of automated increased discretization of the mesh is an absolute benefit to our modeling, reducing time and effort. We have found the software quick and easy for our engineers to train and utilize. I would recommend this product to other geotechnical consulting firms."

  • "The software is well documented and comes with number of useful example models. We were able to quickly begin creating models after a short review of the user interface and going through the available on-line webinars. The software offers solid benefits of less conservatism and the ability to model real geometry."

  • "This new software for stability analysis includes a number of state-of-the-art options for probabilistic slope stability analysis. This feature, combined with comprehensive deterministic analyses, will provide new opportunities to build confidence in the results of a site-specific analysis.”

  • "I'm excited to see the release of this new and innovative product. I look forward to and encourage the application of this software on additional geotechnical projects.”

  • "In consulting engineering practice, I am increasingly made aware of the important and beneficial role that modeling the unsaturated soil zone can play in providing the client with the best possible engineered solution. The SoilVision software has made it possible to readily estimate and incorporate unsaturated soil properties into the modeling of saturated / unsaturated soil systems.”

  • "The use of SVSLOPE® software as part of a research project on clay slopes under seismic conditions with the Université de Sherbrooke has been incredibly easy and effective. The continuation of this research with SoilVision is promising, with technical support, which was present at the right time, as well as a passionate geotechnical team supporting the project.”
