Seismic performance of pile-reinforced slopes
… of discretely spaced vertical precast concrete piles. This study focussed on permanent movement and dynamic response at different positions within the slope, especially at the crest, which would form key inputs into the aseismic design of supported infrastructure. In contrast to previous …

Performance of short piled raft foundation system on peat soil under static load
… was conducted to explore a proposed Short Piled Raft (SPR) foundation system, which is a combination of a pile foundation and raft foundation, with a pile length short enough. The objectives of this research were to optimize pile spacing of SPR foundation system related to its stability, …

Estudo do comportamento de lastros de materiais granulares sobre estacas com capitéis através de modelos reduzidos
… yards made of granular material placed over piles with small circular caps. The importance of the following parameters has been evaluated with the aid of a small scale model: critical thickness of the base in relation to pile spacing and cap diameter, density and grain size distribuition of …

Numerical investigation of load transfer mechanisms in slopes reinforced with piles
… analyses to evaluate the limit soil pressure on piles, to evaluate the load transfer mechanism, and to evaluate alternative means for estimating mobilized and limit loads on piles in piled-slope problems. It is found that limit forces predicted using 2-D, plane strain and 3-D analyses differ …

Behaviour of single batter piles and pile groups under lateral soil movement in sand
Piles are commonly subjected to induced loads from nearby construction activities such as approach embankments, excavation, tunnelling and moving slopes. To better understand the mechanism of this complicated soil-pile interaction problem, a comprehensive experimental and numerical program were …

Optimization of Pile Reinforced Slopes Using Finite Element Analyses
<p>Piles have proven to be an effective means of stabilizing active landslides as well as in marginally stable slopes. Many practical empirical design and analysis methods of slope stability and piled-slope stability have been proposed. However, the solutions of analysis and design methods proposed …

Three dimensional numerical modelling of rows of discrete piles used to stabilise large landslides
… have been carried out to investigate the complex pile-soil interaction effects of single isolated pile and groups of piles. The three-dimensional numerical models developed to carry out these analyses are able to model the full pile-soil interaction problem including three dimensional and surface …

Full Scale Static Lateral Load Test of a 9 Pile Group in Sand
… research has been done to study the effects of spacing in laterally loaded pile groups and how the pile spacing affects lateral resistance of the piles. In this test a 9-pile group of steel piles was installed in a 3x3 configuration in sand. The piles were spaced from center-to-center at a …

THE SHEAR BEHAVIOUR OF THE REINFORCED CONCRETE FOUR-PILE CAPS
… capacity of 2-way spanning reinforced concrete pile caps from bending theory-based empirical design formulae. This causes designers difficulty to predict an accurate shear capacity of the pile cap. The inherently empirical character of the formulae is due to the fact that the formulae have been …

Numerical and physical modelling of piled rafts on soft clay under combined loading
Piled raft foundations are typically used in cases where a shallow foundation is inadequate to sustain the loads of the superstructure either because of lack of capacity or because of excessive displacement. They consist of two components, namely the raft and the pile group, contributing to the …
