The inclusion of a tension crack affects the Limit Equilibrium analysis in two primary ways:

Geotechnical modeling is complex. Slide3 is frequently updated to fix bugs, improve convergence algorithms, and add support for new soil models.

Slide3 offers two distinct methods for handling tension cracks: Automatic and User-Defined.

A slope with a calculated FoS of 1.50 (dry, no crack) may see the FoS drop to 1.20 with an automatic tension crack, and potentially drop to 1.05 if that crack is filled with water. This highlights the sensitivity of slopes to this feature.

This method is used when the location and geometry of a crack are known (e.g., field observations of a scarp).

  • Case Studies: If possible, provide or refer to case studies that demonstrate the practical application of Slide3 in real-world geotechnical projects.
