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 …

Visualization in Geomechanics With an Application to Deep Excavations
… 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 techniques. Finally, …

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 …

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 …

Influência de escavações nos recalques em edificações vizinhas
… is towards the study of the influence of deep excavations on the settlements of adjoining structures. Firstly the data obtained through field instrumentation and direct observation of the construction of several sections of Line 1 of the Rio de Janeiro subway are presented. A study of …

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 …

ANALYSIS AND DESIGN OF EXCAVATION SUPPORT SYSTEM IN SOFT CLAY
Conventional design procedures for deep excavations in soft clay in Singapore are not always adequate. Consequently, difficulties such as large strut loads and excessive ground movements are often encountered. Therefore, a method was proposed for the design of excavation support system in soft …

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 …

Ground movements due to excavation in clay: physical and analytical models
… view of the recent catastrophes associated with deep excavations, there is an urgent need to provide vital guidelines on the design of the construction process. To develop a simple tool for predicting ground deformation around a deep excavation construction for preliminary design and …

Performance monitoring and numerical modelling of a deep circular excavation
For the design of deep excavations, codes and standards advise to base estimates of wall deflections and ground movements on empirical data. Due to the limited number of case studies on circular excavations it is nearly impossible to find comparable projects under similar conditions. Therefore …
