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...
Chinese geologists have warned that an active fault line beneath the planned Yarlung Tsangpo hydropower project could affect the structural stability of one of the world’s most ambitious dam schemes....
A road collapsed suddenly in Rize, Turkey, after ground movement developed beside an active building construction site. The incident occurred in the Islampaşa neighbourhood while foundation excavation...
Tunnel boring has been completed on both tracks of Vienna’s U2 metro extension, marking a major milestone for one of the city’s most important public transport projects. The works form part of the wid...
A comparison of three liquefaction assessment methods for an offshore wind site has found that a fully coupled PLAXIS 2D dynamic analysis using the PM4Sand constitutive model predicted a critical liqu...

Consider the asymmetry at the heart of ground engineering. Site investigation typically accounts for 0.2% to 1.5% of a project's total cost, yet the US National Research Council has observed that unfo...
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...

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....
Ground movement control is a serious subject and key to preventing failure due to loss of serviceability in geotechnical work. For underground excavations, the amount of ground movement is largely dep...
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...
