Rocscience Rs2 Crack |link| Top May 2026

If you're looking for specifics on dealing with a crack at the top of a structure analyzed in RS2 or perhaps details on how to model or interpret results related to cracking in RS2, here are some general points that might be relevant:

📍 Case 2 – Surface Subsidence Over a Tunnel

  • Setting: A 3 km long highway tunnel through sedimentary rock with a set of weak bedding planes at 15 m depth.
  • Model: RS2 with three parallel Crack‑Top layers (0.5 m spacing) to represent the stratigraphy.
  • Result: The model reproduced a double‑hump subsidence profile (≈ 0.35 m peak) that matched laser‑scanning surveys. Sensitivity to joint friction revealed that a 5° reduction (due to water infiltration) would increase subsidence by 30 %.
  • Lesson: Monitoring groundwater pressure on the joint surfaces became a priority for the project.

6️⃣ Common Pitfalls & How to Avoid Them

| Problem | Why it happens | Quick fix | |---------|----------------|-----------| | Non‑convergence after the first load step | Joint stiffness too low → contact algorithm “jumps”. | Increase normal stiffness, add a small penalty damping (0.05–0.1), or reduce the load increment. | | Crack‑Top “sticks” (no opening) even under large tensile load | Friction angle set too high or tensile strength > 0. | Set Friction = 0° for pure tension tests, or lower the Tensile Strength to a realistic value (< σ_t). | | Mesh distortion near the crack | Very coarse mesh + large deformations. | Refine the mesh locally, or enable Remeshing (available in the latest RS2 2025+ builds). | | Unexpected “locking” of the joint | Contact damping too low → oscillations that the solver interprets as “stuck”. | Raise Contact Damping to 0.1–0.2. | | Energy not conserved (large artificial energy spikes) | Incompatible time step in dynamic runs. | Use adaptive time stepping, or manually halve the Δt. | | Results look “symmetric” even though load is eccentric | Model symmetry (mirrored boundary conditions) overriding load. | Double‑check that only the desired side has the point load; disable symmetry planes if you need an asymmetric response. |

Basic Operations

Analysis and Interpretation

  • Linear and Non-Linear Analysis: RS2 offers both linear and non-linear analysis capabilities. Non-linear analysis can be particularly useful for modeling the behavior of rock masses that exhibit non-linear stress-strain relationships, which is often the case when rock is near failure.

  • Probabilistic Analysis: Some versions or modules of RS2 may offer probabilistic analysis tools, allowing users to assess the uncertainty in their models, which is crucial when dealing with complex geological conditions.
