SVSlope® represents the new standard in slope stability analysis. Users can perform classic limit equilibrium slope analysis by the method of slices or newer stress-based methods. Advanced searching methods are implemented to correctly determine the correct location of the critical slip surface.

SVSlope® is characterized by an advanced probability analysis as well as integration with other packages in SVOffice™. The streamlined user interface and advanced slip surface searching algorithms make for fast model setup and computation times.

We have put extensive effort into verifying SVSlope® against classic case-study scenarios and existing slope stability software packages such as Clara/W. Some original interface concepts were inspired by Clara/W and have been implemented in SVSlope® in order to provide continuity of use. The team at SoilVision Systems Ltd. represents an advanced group of geotechnical engineers and software developers with M.Sc. and Ph.D. degrees and decades of experience which ensures that your modeling will be successful and reliable. This allows users to be confident that results from SVSlope® are correct.

SVSlope® is currently being used on world-class slope stability projects. Top slope stability industry experts already support the use of SVSlope® as the new standard in slope stability modeling.

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 modelling 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.
