Three dimensional behavior of retaining wall systems
… interaction (SSI) features of selected earth retaining walls utilizing the nonlinear finite element method (FEM). These 3-D features are not explicitly incorporated in conventional two-dimensional (2-D) procedures that are commonly used to design these retaining walls. The research objective …

Reliability-based design of a retaining wall
A retaining wall is subject to various limit states such as sliding, overturning and bearing capacity, and it can fail by anyone of them. Since a great deal of uncertainty is involved in the analysis of the limit states, the use of detenninistic conventional safety factors may produce a misleading …

Performance of a propped retaining wall at the CTRL, Ashford
… on the field monitoring of a propped bored pile retaining wall installed<br/>in an overconsolidated clay. Pile bending moments, prop loads, pore water pressures and<br/>lateral earth pressures were logged automatically at intervals of up to 5 minutes<br/>throughout construction (and for 4 years …

Sand Deformation Mechanisms and Earth Pressures Mobilised with Retaining Wall Movements
The conventional design of retaining walls is typically based on ultimate limit state calculations with arbitrary factors of safety, while the assessment of wall deformations is based on serviceability limit state calculations. Such an inconsistency has caused much uncertainty and hence inevitably …

Application of new observational method on deep excavation retaining wall design in London Clay
… study shows savings can be achieved on embedded retaining wall design for deep excavation in London Clay through the observational method, without compromising safety. Despite the inherent benefits of the method and its acceptance by design codes, the application of the observational method for …

Numerical Analysis on Seismic Response of Cantilever Retaining Wall Systems and Fragility Analysis on Motion Response
In this investigation, seismic response of retaining walls constructed with cohesive and cohesionless backfill materials was studied. Fully dynamic analysis based on finite difference method was used to evaluate the performance of retaining walls during the earthquake. The analysis response was …

Influence of heave reducing piles on ground movements around excavations
… acting at formation level and against the retaining wall. The fluid support was removed as the test proceeded and successive levels of props were advanced against the retaining wall using pressurised hydraulic cylinders as jacks. Ground movements were measured using a combination of …

Seismic Behaviour of Retaining Walls with Adjacent Structures
… representing a container crane, a cantilever retaining wall, and liquefiable sand. Two models without a structure behind the retaining wall are considered benchmark tests. Seven dynamic centrifuge tests were conducted to study the effects of various factors on the behaviour of the …

A site-based study of durability indexes for concrete in marine conditions
… elements in the Port viz. a reinforced concrete retaining wall and mass concrete paving slabs. This was to facilitate possible future correlation or further study. For closer correlation, test elements were cast in close proximity of the actual retaining wall and likewise for the slabs.

An analytic hierarchy process and Markov chain based approach for condition rating and dynamic service life prediction of retaining walls
Retaining walls are typically considered auxiliary assets within the global transportation asset management scheme. However, failure cases to this structure class have attracted more attention to retaining wall assets. The possibility of failure also helps validate Moving Ahead for Progress in the …

Experimental study of earth pressures on retaining structures
… studies of earth pressures exerted on retaining structures and laboratory studies of the at-rest earth pressure coefficient are summarized. The current methods used to evaluate the earth pressures due to compaction are reviewed. The design features of a new instrumented oedometer …

Determination of Seismic Earth Pressures on Retaining Walls Through Finite Element Analysis
<p>Seismic pressures on displacing or rigid retaining or basement walls have been derived based on the original work of Mononobe and Okabe, who used a shake table to calculate dynamic pressures of displacing retaining walls existing in cohesionless soils. Since this original work was done over …

Development of an extended hyperbolic model for concrete-to-soil interfaces
… and compaction of the backfill behind an earth retaining wall may induce a vertical shear force at the soil-to-wall interface. This vertical shear force, or downdrag, is beneficial for the stability of the structure. A significant reduction in construction costs may result if the downdrag is …

Elements of Memory
… up remote hollows. This place is created by a retaining wall to hold back the slope and a generous roof to shelter from the weather. The structure is divided into two seemingly equal halves, one half being enclosed to form the house, the other remaining for outdoor space. Terrain and …

Approaching The Smokestack and Wall
… creates a connection with the past. Formed by a retaining wall and smokestack, an outdoor room is the destination from which two paths direct the inhabitant. This room divides the site and is surrounded by two buildings designed as a library. Through the use of additional architectural elements, …

Stress disturbance on the cyclic behavior of soils and its impact on geotechnical structures
… lateral excavation is simulated by translating a retaining wall between loading cycles. The cyclic loading-induced footing settlement behavior and the earth pressure in ground are presented and discussed under different lateral displacements of the retaining wall. An empirical model is proposed to …
