About

sSLOPE

Perform quick slope stability analyses on your mobile device. This app uses the simplified Bishop method to calculate the Factor of Safety for soil and rock slopes, supporting various conditions like water tables, external loads, and seismic forces.

Highlights
  • Analyze horizontally layered soil slopes (up to 7 layers)
  • Incorporate water table effects and ponded water
  • Apply vertical external loading
  • Model pseudo-static seismic loads
  • Simulate End Anchored and Soil Nail support
  • Adjust failure surface search limits
  • Utilize Mohr-Coulomb and Hoek-Brown strength criteria
  • Generate and email PDF reports

sSLOPE is designed to perform a quick slope stability analysis on your phone device. sSLOPE is very simple and easy to use. sSLOPE uses the simplified Bishop method (method of slices) to discretize the soil/rock mass and determine the Factor of Safety (FOS). sSLOPE has the following features: • The stability of horizontally layered soil slope (up to maximum 7 layers) can be analyzed using the latest version (i.e. sSLOPE v3.0). • Water Table can be used for calculating pore pressure. The Water Table can also be used to define ponded water above the slope surface. • Vertical external loading (compression distributed pressure) can be easily applied to the upper slope of a model. • Pseudo-static seismic loads can be added to model by defining the seismic load coefficients in the horizontal and/or vertical directions. • The End Anchored and Soil Nail support can be used to model slope reinforcement. • Failure surface search limits can be modified to narrow down the search area to achieve better accuracy. • Both Mohr-Coulomb and Generalized Hoek-Brown strength criterion can be used to assess stability of soil and rock slopes. • The Settings Tab can be used to configure the main analysis parameters for the model, such as Units of Measurement, Project Title and etc. • The brief summary of analysis results and input data will be displayed in the Report Page. The report button, allows user to save the current model’s input and output information into PDF file. The generated report file can be sent out via email.

Verdict

The call

The clearest difference is rating: sSLOPE at 4.0 against Geological Field Notes's 1.0. sSLOPE also leads on price ($3.99 vs $4.99). Geological Field Notes's advantage is update cadence (every 3 months vs every 27 months) and iOS requirement (12.0 vs 15.6). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.
