Cyclic and Rapid Axial Load Tests on Displacement Piles in Soft Clay

Axial resistance of CFA piles in Dublin Boulder Clay

Centrifuge modelling of sand compaction piles in soft clay under embankment load

Sand compaction piles are used in practice for ground improvement of soft subsoil in order to accelerate consolidation, reduce compressibility, and increase strength. The current design procedure of sand compaction piles is based on simple empirical calculations, which does not take full account of the sand pile behaviour. This research project investigates the behaviour of a base reinforced em...

Centrifuge Studies of Cyclic Lateral Load-displacement Behavior of Single Piles

Lateral Load Tests on Small-Diameter Piles for Slope Remediation

Slope reinforcement and the use of structural pile elements can be an effective slope remediation alternative when conventional remediation practices (e.g., improved drainage) fail to consider the causal factors leading to slope instability (e.g., strength loss due to weathering). An experimental research program was aimed at developing a rapid, cost-effective, and simple remediation system tha...

Interpreting Strain Measurements from Load Tests in Bored Piles

In static load tests vibrating wire strain gages are generally used. The advantage of vibrating wire sensors over more conventional electrical resistance or semi-conductor types lies mainly in the sensor output, which is a frequency rather than a voltage or resistance. The frequency output is easier to transmit over long cables and is unaffected by voltage drops such as those which can be broug...
