Analysis and design of reinforced embankments: Methodology, implementation and impact of critical parameters
(2010)This paper outlines the basic principles of analysis and design of reinforced embankments, according to the 'Design & Construction Guidelines' of the U.S. Department of Transportation, which are based on limit equilibrium ... -
Design of reinforced embankments: Limit equilibrium and numerical methods
(2010)The aim of this paper is a comparative study of a reinforced embankment using two different design approaches. The first methodology is based on the limit equilibrium approach and the fundamental aspect of achieving ... -
Effect of Cracking on the Response of Pile Test under Horizontal Loading
(2009)Capacity-based design of structures limits the soil-structure interaction mechanism to the determination of the bearing capacity of a pile group. However, in many cases the criterion for the design of piles to resist lateral ... -
Effects from diaphragm wall installation to surrounding soil and adjacent buildings
(2013)A new approach for simulating the excavation and construction of subsequent panels is proposed to investigate the effects from the installation of diaphragm walls on the surrounding and adjacent buildings. The method has ... -
Evaluation of negative skin friction effects in pile foundations using 3D nonlinear analysis
(2005)The aim of this paper is to evaluate the influence of negative skin friction in pile foundations. Three dimensional nonlinear analyses for a single pile and pile groups were carried out for a specific case and some case ... -
Explicit extension of the p-y method to pile groups in cohesive soils
(2013)Although simplified numerical methods are reliable for evaluating the response of a single pile under horizontal load, their application is questionable for assessing the response of pile groups. The notion of "p-y" curves ... -
Explicit extension of the p-y method to pile groups in sandy soils
(2014)The method of "p-y" curves has been extensively used, in conjunction with simplified numerical methods, for the design and response evaluation of single piles. However, a straightforward application of the method to assess ... -
Interaction of retaining structure with adjacent building: Multi-stage numerical analysis
(2012)Large settlements induced to a multi-store building at the initiation of the construction of a diaphragm wall led to a demand of re-dimensioning the initial retaining measures. To achieve this target a multi-stage numerical ... -
Numerical assessment of axial pile group response based on load test
(2003)Axial pile load tests are considered within the design procedure of most major construction projects that include pile foundations, aiming to determine both the ultimate bearing capacity and the pile stiffness at working ... -
Numerical Assessment of Subsidence and Adjacent Building Movements Induced by TBM-EPB Tunneling
(2014)A three-dimensional (3D) numerical model simulating a twin tunnel excavated by a tunnel-boring machine (TBM)-earth-pressure balance (EPB) is presented. All relevant components are taken into account, and the influence of ... -
On the response prediction of horizontally loaded fixed-head pile groups in sands
(2010)The aim of this paper is to investigate the behavior of laterally loaded pile groups in sands with a rigid head and correlate the response of a pile group it to that of a single pile. For this purpose, a computationally ... -
Pile foundation analysis and design using experimental data and 3-D numerical analysis
(2009)Capacity based design of pile foundations limits the soil-structure interaction mechanism to group bearing capacity estimation, neglecting, in most cases, the contribution of the raft. on the other hand, a straightforward, ... -
Response evaluation for horizontally loaded fixed-head pile groups using 3-D non-linear analysis
(2005)The response of laterally loaded pile foundations may be significantly important in the design of structures for such loads. A static horizontal pile load test is able to provide a load-deflection curve for a single free-head ... -
Response evaluation of axially loaded fixed head pile groups using 3D nonlinear analysis
(2004)The aim of this paper is to evaluate the influence of the interaction between the piles of a group fixed in a rigid head on both its bearing capacity and the stiffness of the group. For this purpose, a parametric ... -
Response evaluation of axially loaded fixed-head pile groups in clayey soils
(2009)The aim of this paper is to investigate the interaction between the piles in a group with a rigid head and correlate the response of a group of piles to that of a single pile. For this purpose, a computationally intensive ... -
Response evaluation of horizontally loaded pile groups in clayey soils
(2012)The aim of this paper is to investigate the behaviour of laterally loaded pile groups with a rigid head, and correlate the response of a pile group to that of a single pile. For this purpose, a computationally intensive ... -
Response of pile groups in clays under lateral loading based on 3-D numerical experiments
(2010)The response of laterally loaded pile foundations may be significantly important in the design of structures for such loads. Although simplified numerical methods are reliable for evaluating the response of a single pile ... -
Response prediction for axially loaded pile groups in clays using 3D nonlinear analysis
(2005)The objective of this paper is to quantify the effect of the interaction between the piles of a group under axial loading in clayey soils. Three dimensional parametric nonlinear analysis was carried out for various pile ...
