Excavations with Tiebacks and Rock Anchors
Anchored Walls - Information and Construction Sequence Anchored walls have become popular in braced excavations because of a) the substantial progress in the technology and availability of high-capacity anchor systems, and b) the absence of interior obstructions that permit uninterrupted earth moving and thus improve the construction conditions of the underground portion of a building (Xanthakos, 1994). Figures 1 and 2 show a photo and a schematic of tied-back slurry wall exc

Optimizing an Anchored Excavation Design with DeepEX
DeepEx Software Automatic Optimization Options Designing anchored excavation systems is an inherently iterative process. Engineers must satisfy both structural and geotechnical requirements while maintaining an efficient and constructible solution. In many cases, the initial design meets some criteria but fails others, requiring multiple adjustments before reaching an optimal configuration. DeepEX streamlines this process by combining rapid model generation, robust analysis m
Failure of a Test Embankment on Sensitive Champlain Clay
Revisited with DeepEX software 1- Introduction The failure of a test embankment constructed on sensitive Champlain clay at Saint-Alban, Québec, remains one of the most instructive case histories in geotechnical engineering. The experiment was conducted to investigate the behaviour of embankments on soft clay foundations and was extensively documented by La Rochelle et al. (1974). The study included detailed monitoring through vane tests, settlement measurements, pore pressure
Surface Settlements of a Surficial TBM Tunnel
Evaluation with DeepEX software 1. Introduction Mechanized tunnelling in urban environments requires careful assessment of surface settlements to protect overlying infrastructure and buried utilities. Surface deformations depend on soil stiffness, tunnel geometry, construction method, and time‑dependent consolidation, and are often evaluated using empirical Peck‑type troughs, analytical solutions, or finite element (FEM) models (Peck, 1969). Recent case histories of shield tu
Design Smarter, Not Harder – Choose DeepEX

🌍Geoengineering Master Class #4
Why Construction Staging Is Critical in FEM Analysis and How DeepEX Makes It Practical Introduction Finite Element Analysis (FEM) has become an essential tool in geotechnical engineering, especially for deep excavations and underground structures. FEM allows engineers to capture soil–structure interaction, stress redistribution, and deformation patterns with a level of detail that simpler methods cannot provide. However, the accuracy of FEM does not depend only on soil models
Basal Heave Analysis in Soft Clays
Basal Heave Calculations with DeepEX Software Introduction Basal heave is a well-documented failure mechanism in deep excavations constructed in soft to medium undrained clays. As excavation progresses, stress relief beneath the base may trigger upward movement of the clay, leading to sudden loss of stability. Classic failures reported by Bjerrum and Eide (1956) and later discussed by Terzaghi, Peck, and Mesri (1996) demonstrate that basal heave can occur even when wall movem

Diaphragm Walls in Deep Excavations
Concrete Diaphragm Walls (Slurry Walls) The continuous diaphragm wall (also referred to as slurry wall in the US) is a structure formed and cast in a slurry trench (Xanthakos, 1994). The trench excavation is initially supported by either bentonite or polymer based slurries that prevents soil incursions into the excavated trench. The term "diaphragm walls" refers to the final condition when the slurry is replaced by tremied concrete that acts as a structural system either for
Soil Mix Walls in Deep Excavations
Soil Mix Walls - Plain Concrete Piles Use of the Soil Mix Walls Soil mix walls are constructed by mixing and partly replacing the insitu soils with a stronger cement material. Various methods of soil mixing such as mechanical, hydraulic, with and without air, and combinations of both types have been used widely in Japan for about 20 years. Soil mixing has been used for many temporary and permanent deep excavation projects including the Central Artery project in Boston. Known
Secant & Tangent Pile Walls in Deep Excavations
Secant/Tangent Piles: Construction, Use, Advantages and Disadvantages Secant pile walls are formed by constructing intersecting reinforced concrete piles. Secant pile walls are reinforced with either steel rebar or with steel beams and are constructed by drilling under mud. Primary secant piles are installed first with secondary reinforced secant piles constructed in between primary piles once the latter gain sufficient strength. Pile overlap is typically in the order of 3 in
Sheet Pile Walls in Deep Excavations
Sheet Pile Walls - Advantages & Disadvantages Sheet pile walls are constructed by driving prefabricated sections into the ground. Soil conditions may allow for the sections to be vibrated into ground instead of it being hammer driven. The full sheet pile wall is formed by connecting the joints of adjacent sheet pile sections in sequential installation. Sheet pile walls provide structural resistance by utilizing the full section. Steel sheet piles are most commonly used in dee
Soldier Pile & Lagging Walls in Deep Excavations
