A Comparative Assessment Using LEM Analysis Introduction The use of apparent earth pressure diagrams remains a cornerstone in the design and verification of retaining systems, especially for excavations supported by sheet piles, soldier piles, or diaphragm walls. Traditional approaches such as the Active Earth Pressure Method (Rankine or Coulomb), Peck’s Apparent Pressure Envelope (Peck, 1969), and the FHWA Apparent Pressure Method (O’Rourke and Clough, 1990) provide valuable

Performance of the Helical Piles P-2 and P-3 Using DeepFN D 1. Introduction This article reviews the axial performance of two single helical piles installed in a glaciolacustrine clay deposit in Edmonton, Canada, as documented by Lanyi-Bennett and Deng (2019). The field results provide a reliable basis for calibrating DeepFND simulations involving double-helix piles in cohesive soils. The study focuses on piles P-2 and P-3, examining their measured behaviour and comparing it

How to Determine Realistic Prestress Loads for Ground Anchors in DeepEX Ground anchors play a crucial role in the performance of deep excavations. Before the wall ever reaches its final depth, anchors begin resisting active soil pressures stage by stage, helping control wall movements and ensuring structural safety. But a common challenge engineers face is determining what prestress load  should be applied to each anchor level so that the system responds realistically once co

Learn. Design. Master Geotechnical Engineering with Confidence. A New Learning Experience by Deep Excavation LLC Geotechnical design is complex — but mastering it shouldn’t be.That’s why Deep Excavation LLC  created the Geoengineering Master Class , a new monthly training series dedicated to helping you understand, design, and optimize real geotechnical structures. Each Master Class dives into a practical engineering case — from deep excavations and foundations to slope stabi

Innovation and the Future of Geotechnical Engineering We invite you to watch this special episode of Director’s Cut , where Geo-Institute Director Brad Keelor  interviews Dimitrios Konstantakos , CEO of Deep Excavation LLC . In this inspiring conversation, Dimitrios shares his journey from engineer to industry leader, offering insights into innovation, technology, and the evolution of geotechnical engineering . He discusses how visionary thinking and practical experience have

A Reappraisal Using SnailPlus Introduction Baker (1994) describes what is believed to be the first major soil-nailed excavation in the UK, constructed in 1988 at Rover’s Longbridge works. The scheme required a near-vertical excavation, up to 10 m high and 50 m long, to create space for a new paint shop. The excavation was complicated by surcharge loads from nearby structures (a water tank, buildings, and a conveyor bridge), as well as a disused brick-lined tunnel intersecting

Reliability Analysis VS Deterministic Design Introduction In geotechnical engineering, uncertainty is not the exception, it is the rule. Soil is a naturally variable material, and its properties can change significantly even within a single project site. Deterministic analysis, which relies on single “characteristic” values for soil parameters, often simplifies this variability into a single calculation. While practical, this approach can obscure the real range of possible ou
