India’s Mumbai-Ahmedabad high-speed rail project has reached a major underground construction milestone, with the country’s largest rail tunnel boring machine beginning excavation from the Vikhroli sh...
A fatal landslide at the under-construction Anakkampoyil-Kalladi-Meppadi road tunnel project in Kerala has renewed concern over construction-stage slope stability in the Western Ghats. The landslide o...
Researchers in China have investigated how a new X-shaped railway sleeper could improve the response of ballasted track to impact loading. The study compared conventional I-shaped sleepers with X-shap...
The Georgia Tech Geosystems group has released digital scans of course notes taken by Prof. George F. Sowers during his graduate studies at Harvard University in the late 1940s, offering the geotechni...
Railway cuttings can be among the most sensitive geotechnical assets on transport networks. They are often steep, weathered, difficult to access and located directly beside live operational infrastruc...

Helical piles and anchors are widely used in foundation construction due to their efficiency, versatility, and performance. However, specifying them correctly is critical to ensuring both structural r...
Our understanding of ground conditions evolves with the project, so geotechnical design teams need a reliable way to work with the latest information. Seequent’s OpenGround Civil 3D Extension creates...
What if checking every section along your tunnel took less time than making a coffee? Tunnel lining design is not painful during the analysis stage – the work gets bogged down afterward. Once RS3 has...
If you design infrastructure in Autodesk Civil 3D and you have outgrown manual borehole imports, the most complete option available today is GeoDin® Ground - a free app on the Autodesk App Store that...
Samuel DeMott and Matt Redfern have written a feature story in May/June's issue of ADSC Foundation Drilling Magazine discussing the California High-speed Rail Dutch John Cut and Cole Slough Bridge Fou...

Floating offshore wind is advancing quickly, but one of its practical challenges remains the safe and efficient connection of dynamic power cables in open sea conditions. A new approval milestone for...
Subsurface injection and production are critical to energy, water, and carbon management—from conventional and unconventional oil and gas to wastewater disposal, geothermal energy, and carbon storage....
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...
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...
