A shallow earthquake has struck southern Spain, injuring at least three people and damaging buildings in and around Granada. The tremor hit at 10:37 local time (08:37 GMT) on Tuesday, about 10 km sout...
Amtrak has reopened Line 2 of the East River Tunnel in New York, completing the first major phase of a $1.6bn rehabilitation programme on one of the busiest passenger rail tunnel systems in the Wester...
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...
A powerful 7.7 magnitude earthquake has struck Indonesia’s Flores region, killing at least 53 people, injuring more than 100 and leaving thousands unable to return home. The shallow earthquake hit ear...
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...

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...
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...
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...
Introduction: Unlocking Automation in Geotechnical Engineering As engineering projects continue to grow in scale and complexity, engineers increasingly rely on automation to improve efficiency, consis...
A PLAXIS 2D dynamic finite element study of offshore monopile driving has found that excess pore pressure generated by hammer blows can reduce soil resistance to driving by up to 62%, a mechanism the...

A circular feature first noticed on Google Maps has led scientists to identify a previously unrecognised meteor impact structure in remote Quebec. The structure, now named Uhackatik, is reported in th...
This course is for those who have never used GeoStudio before or have not upgraded to a recent version in a long time and want a refresher. It provides an overview of the basic components of setting u...
UC Berkeley faculty does it again! The "Geotechnical Earthquake Engineering" series is offered from September to November 2026 and consists of three short courses and focuses on key concepts and recen...
The analysis of retaining structures is commonly approached in three progressively more advanced levels, depending on the complexity of the wall system, the ground conditions, and the need to predict...
The Critical Role of Groundwater Water is the single most destructive element in retaining wall stability analysis. While designers account for the dry unit weight (γd) or saturated unit weight (γsa...
A cantilever sheet pile wall supporting a 3.5 m deep excavation in dry sand (γdry = 15.3 kN/m³, φ′ = 35°, c′ = 0) is to be constructed. Determine the required depth of embedment. 1. By using the...
A sheet pile wall is a line of interlocking thin wall elements driven into the ground to form a continuous barrier that can retain soil and/or water. Stability comes from penetration below the exc...
Design for a cantilever retaining wall supporting 3.0 m of dry sand backfill. The wall has a 3.20 m base (1.00 m toe, 1.90 m heel), a 0.30 m thick stem, and a 0.45 m thick footing; concrete unit wei...
The geotechnical stability of a retaining structure is assessed using limit equilibrium methods, which determine the ratio of available resisting forces/moments to the driving forces/moments. This ra...
Introduction to Lateral Earth Pressure Soil, unlike a true fluid, exhibits both density and internal friction (φ) and cohesion (c). Consequently, the pressure it exerts horizontally on a retaining s...
