World's largest double-shield hard-rock TBM completed for 18.4 km Sichuan expressway tunnel
China has completed what is described as the world's largest-diameter double-shield hard-rock tunnel boring machine, developed for excavation of the 18.4 km Yuexi Tunnel on the Jinkouhe-Xichang Expres...
Guarding the golden pharaoh: how advanced modelling is protecting Tutankhamun’s tomb
In Egypt’s Valley of the Kings, carved into the fragile shale cliffs of Luxor, lies one of the world’s most celebrated discoveries: Tutankhamun’s tomb. Known as KV62, the burial chamber of the boy pha...
Kansas City completes major flood protection upgrade along Missouri and Kansas rivers
A major flood risk management programme has been completed in Kansas City, upgrading some 17 miles of levees and floodwalls along the Kansas and Missouri rivers to strengthen protection for residents,...
The opportunity for seismic in mining
Mining is an inherently uncertain business. Information about the underground is sparse and increasingly more expensive to collect. In the not so distant past, companies drilled extensive grids to cre...

Why Builders Are Turning to Helical Piles for Residential Construction
In today's residential and multifamily construction market, builders face increasing pressure to control costs, accelerate schedules, and build on sites that would have been considered unbuildable jus...
Behavior of Square-Round Shaft Combination Helical Piles and Anchors
Historically, most helical anchors and piles have been fabricated with helices attached to either a solid square or open pipe central shaft (Square-Shaft (SS) or Round-Shaft (RS)). This is generally h...
Slide2 Expands Probabilistic Modeling with Anisotropic Spatial Variability and Conditional Random Fields
Real geology doesn't obey global x-y axes, and it certainly doesn't ignore the borehole logs sitting on your desk. Slide2's Spatial Variability feature already allows engineers to represent uncertain...
Helical Piles Help Rebuild Storm-Damaged Boardwalks in Remote Alaska
A powerful tropical cyclone, Typhoon Halong developed near Iwo Jima, Japan on October 3, 2025. Four days later, after transitioning into an extratropical cyclone, the storm hit western Alaska, deliver...
Three-Dimensional Numerical Analysis of a Large-Diameter Surge Shaft Using RS3
Introduction Large underground excavations rarely behave as isolated, uniform openings. As excavation progresses, the surrounding rock mass redistributes stress, support is activated, and adjacent ope...

Numerical Modelling of Geogrid-Reinforced Systems
Analytical and Limit Equilibrium Methods Analytical calculations are useful for preliminary tensile demand, pullout and load-transfer checks. Limit equilibrium methods are widely used for reinforced...
Construction Sequence and Quality Control
The performance of reinforced soil depends heavily on construction. Even a correctly designed product can be compromised by poor orientation, damage, inadequate compaction or uncontrolled water. The g...
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...
Design Philosophy and Governing Checks
From Product Property to Design Resistance Design begins by defining the problem, the governing limit states, the design life, the ground conditions and the construction sequence. Index product data...
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...
