# Slide

<b>2D Limit Equilibrium Slope Stability Analysis</b><br><br> <i>Slide</i> is a slope stability analysis program for soil or rock slopes. <i>Slide</i> provides a comprehensive array of analysis features, including support design, integrated finite element groundwater (seepage) analysis and probabilistic analysis. The CAD based graphical interface offers a wide range of modeling and data interpretation options that enables you to perform fast, thorough and accurate analyses. Files can be imported into <i>RS2</i> for finite element stability analysis. <br><br>For a comprehensive program overview, including a description of available features and options, see the <a href="http://rocscience.com/help/slide/webhelp7/Slide.htm">Online Help</a>.

### Model Editing

### Materials

- How can I model a HDPE membrane in Slide?
- Can I import material properties from one Slide file into another?
- Is there a way to know which portion of a non-circular failure surface is assigned a particular strength when using an anisotropic material?
- How can I perform a statistical analysis in Slide using anisotropic materials?

### Slip Surfaces and Factor of Safety

- Can I carry out a probabilistic analysis on a single slip surface that I define?
- How can I change the number of decimal places displayed in FS?
- What does it mean if I get an error message for a slip surface?
- Can Slide be used to calculate FS against uplift for a dam?
- How can I determine the volume or weight of material that may slip, based on the failure surface?
- Why do I have negative interslice forces towards the crown of the failure surface?

### Slope Support

- What does "Show Support Forces" do?
- What properties should I use for geogrid and geotextile reinforcement?
- Is the soil nail capacity the ultimate or allowable capacity?
- In a sensitivity analysis, what soil nail properties can be varied?
- How is soil nail capacity computed when both tension and shear options are selected?
- Can pre- or post-tensioning be modeled in Slide?

### Seismic

### Groundwater

- What does the Water Table Location sensitivity plot show?
- How can I model a lined pond (account for weight of ponded water, with zero pore pressure in slope)?
- Are flow quantities presented per unit length?
- When using a pore pressure grid, is there a way to exclude a material?
- What is the difference between a piezo line and a water table?
- Is a total or effective stress method better for stability computations?
