Reliability Analysis of Braced Excavations
… evaluating the probability of failure of braced excavations through three critical modes of failure, namely buckling of struts, heaving of the base, and excessive settlement of the adjoining ground. The method was applied to braced excavations in medium to soft clays (mainly in Japan), and a …

Interactive design of braced excavations
Construction of braced excavations in major urban areas has increased over the last few decades. It is a major concern of the designer to limit ground movement around an excavation in order to prevent damage to adjacent structures, utilities and roads. Existing design methods can accurately predict …

Finite Element Analysis of Deep Excavations
… SAGE, and research on the performance of deep excavations. SAGE was developed at Virginia Tech for analysis of soil-structure interaction problems (Morrison, 1995). The purpose of the work described in this text with SAGE was to increase the capabilities of the program for soil-structure …

A Reassessment of the Excavations at Tall Safut
… have been published since the conclusion of excavations in 2001. The site has received only brief mention in other articles and books dealing with archaeology because of its remains dating to the Middle Bronze Age, Late Bronze Age, and Iron Age. However, there is a significant gap in the …

Visualization in Geomechanics With an Application to Deep Excavations
The second part of this dissertation explores the behavior of deep excavation numerical analyses, with the aid of the visualization techniques presented herein. First, a 2D plane strain excavation analysis is explored. Second, a 3D linear excavation is modeled using a variety of excavation …

Textile Production Tools from the Excavations at Caere, 2012 — 2014.
… the textile production tools from the 2012–2014 excavations at Caere, an Etruscan city northwest of Rome. While all textile tool finds — loom weights, spools, and spindle whorls — are presented, the discussion is focused on complete loom weights. The likely loom set-up, thread type, and …

Influence of heave reducing piles on ground movements around excavations
… the influence of piles, installed beneath deep excavations, as a means of reducing movements in the surrounding ground. The work focussed on the use of piles installed as a part of top down basement construction, a technique used in conjunction with deep excavations in urban areas. The …

Integration of Numerical Modeling and Field Observations of Deep Excavations
The final chapter of this thesis includes the application of SelfSim to extract the soil constitutive behavior directly from field measurements of two excavation case histories. SelfSim is able to extract sufficient information on soil behavior to capture measured excavation response in multilayer …

Response of piled buildings to the construction of deep excavations
Trends in the construction of deep excavations include deeper excavations situated closer to buildings. This research provides insight into mechanisms of soil-structure interaction for piled buildings adjacent to deep excavations to be used in the design and monitoring of deep excavations in urban …

Numerical upper and lower bound limit analysis for braced excavations
… methods in evaluating the stability of braced excavations.

MOVEX: interactive design of braced excavations to limit ground movements
… program for the design of structurally supported excavations to limit X lateral ground movements in clay soils, was revised and updated. A key element in the program, the method of determining factor of safety against basal heave, was fully rewritten. Seven case histories were examined to evaluate …

Basal Stability of Braced Circular Excavations in Isotropic and Anisotropic Clays
… the stability of basal heave in braced circular excavations in undrained soft clays. This analysis was conducted using the finite element method, focusing on both isotropic and anisotropic strength conditions. The initial study utilized the classic Mohr-Coulomb elastic-perfectly plastic …

Analysis of Ground and Building Response Around Deep Excavations in Sand
Ground-structure interaction around deep excavations is investigated by superposing different types of structures in the zone of influence of excavation, in 2D and three-dimensional (3D) models. Ground movements modified by the structures are sensitive to the assumptions regarding one of the state …

Supervised learning for back analysis of excavations in the observational method
… raises concerns since movements caused by deep excavations might damage adjacent buildings. Unfortunately, the prediction of geotechnical behaviour is difficult due to uncertainties and lack of information of on the underground environment. Therefore, to ensure safety, engineers tend to choose …
