Spatial Safety Maps from RS3 SSR Results: A Python Post-Processing Workflow
Introduction Shear Strength Reduction (SSR) analysis is a well-established method for assessing the stability of slopes and other geotechnical infrastructure, including open pits. In RS3, SSR yields a...
PLAXIS 3D Study Finds Winged Piles Can Cut Uplift Settlement by Up to 95% in Sandy Soil
A PLAXIS 3D numerical study of under-reamed 'winged' piles in sandy soil has found that adding a wing near the pile tip can cut uplift-induced settlement by up to 95% compared with a conventional stra...
Combining PLAXIS 2D and 3D Kept the Lueneburg Lock's Century Project Within 4 mm of Its Historic Neighbour
Engineers designing the new Lueneburg Lock in northern Germany used a deliberately complementary combination of PLAXIS 2D and PLAXIS 3D models, rather than a single large 3D model, to control a 30 m d...
A New Versatile Ground Motion Manager: Bringing Target Response Spectrum-Consistent Uni- and Bi-directional Ground Motion Selection into RSSeismic
Ground motion selection is a key part of seismic site response analysis, representing the ground shaking driving the soil column. In preparing for a site response analysis, engineers define the seismi...

Simplified Worked Example: Internal Stability of a Reinforced Soil Wall
This example demonstrates two basic internal checks for a 6.0 m high geogrid-reinforced soil wall: tensile rupture and reinforcement pullout. It is intentionally simplified, uses level granular backfi...

Principal Geotechnical Applications
Mechanically Stabilized Earth Walls In an MSE wall, horizontal layers of geogrid extend from the facing into compacted structural backfill. The soil tends to move laterally, while the reinforcement c...
Engineering Properties and Laboratory Testing
Tensile Force-Strain Response Geogrid tensile properties are normally reported as force per unit width, such as kilonewtons per metre. The full force-strain curve is often more useful than the ultima...
Reinforcement and Stabilization Mechanisms
Tensile Reinforcement The most fundamental mechanism is tensile reinforcement. As the soil mass tends to deform, relative movement develops between the soil and the geogrid. Interface shear and beari...
Geogrids and the Concept of Reinforced Soil
What Is a Geogrid? A geogrid is a planar geosynthetic product formed by connected tensile members that create a regular or quasi-regular network of openings, known as apertures. It is installed withi...
