Collapse of Reinforced Soil Wall Due to Steel Strip Corrosion

Corrosion of the steel strips has caused the collapse of the reinforced soil retaining wall, with the detachment of the front panels. This structural failure highlights the importance of protection processes against oxidation in containment systems, especially in aggressive environments or those with drainage deficiencies.

3D Modeling of the Structural Failure with ContextCapture and Plaxis 3D 🏗️

For the collapse analysis, ContextCapture was used, generating a point cloud and a mesh model of the post-failure state. With Plaxis 3D, the soil-structure interaction was simulated, evaluating the loss of bearing capacity of the corroded strips. The model allowed identifying that the reduction of the steel area due to localized corrosion generated tensile stresses exceeding the yield limit, triggering buckling and sequential rupture of the panels.

Steel rusts, but the panels fly on their own 😅

Apparently, the steel strips decided to retire early, leaving the front panels unsupported. The result: a wall that seemed sturdy but was actually doing a handstand. Now we have to explain to the client that the problem wasn't the soil, but that the steel took being a consumable material very seriously. Good thing 3D modeling allows calculating the repair budget with millimeter precision.
