Dynamic Analysis Of Offshore Structures
This study comprises three main parts: (1) Pile Driving Analysis. The conventional one dimensional wave equation analysis of the pile driving problem suffers from the empirical representation of the soil parameters. In this study, an improved one dimensional wave equation model is developed which …

Interação de sistemas solo-estaca submetidos a solicitações dinâmicas
… is to present a method of analysis for dynamic soil-pile interaction. An analytical solution in frequency domain is developed for horizontal vibration and circular cross section, modelling the soil as a linear viscoelastic material. A comparison with the model of lumped mass is performed for …

A Hybrid Approach for Nonlinear Soil-Structure Interaction Analysis of Pile- Supported Bridges
The large-diameter reinforced concrete pile shafts are commonly designed as an economical solution for foundation of highway bridges in soft soils. The substructure method is a widely used technique for seismic SSI analysis of pile-supported bridges due to its remarkable computational efficiency. …

Dynamic Pile-Soil Interaction in Laterally Spreading Slopes
… to deep foundation systems. However, the dynamic soil-structure interaction between liquefied soil and piles is extremely complex and further work is required to define the appropriate design pressures and to understand the mechanisms at work. This thesis presents the findings of an experimental …

Impact of Jet Grouting on the Lateral Strength of Soil Surrounding Driven Pile Foundations
Jet grouting was used to strengthen the soft soil surrounding the piles and the pile cap of two full-scale driven pile foundations. Soilcrete columns, created by jet grouting, were placed underneath the pile cap and surrounding the piles of the first foundation. Two rows of soilcrete columns were …

Seismic performance of pile-reinforced slopes
… of such slopes in non-liquefiable granular soils has been investigated and an extensive programme of centrifuge testing was conducted to quantify the improvements to seismic slope performance which can be achieved by installing a row of discretely spaced vertical precast concrete piles. This …

Dynamic Full-Scale Testing of a Pile Cap with Loose Silty Sand Backfill
Pile caps are used in foundation design to aid multiple single piles to act as a pile group to resist lateral forces that may cause overturning moments. The pile cap and pile group resist these forces by pile-soil-pile interaction, base and side friction along the pile cap-backfill interface, and …

ANALYSIS OF THE EFFECTS OF HEAVILY LOADED MAT FOUNDATION ON ADJACENT DRILLED SHAFT FOUNDATION
… this situation cannot be avoided, influence of soil pressures and deformations in soil, created by shallow foundation on adjacent deep foundation, must be evaluated. The study of interaction between deep foundations has been carried out by several researchers in terms of pile-soil-pile …

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 …

Piles in Sand and in Sand Overlying Clay
… of single 60mm and 114mm segmented tubular steel piles driven and placed into loose sand and loose sand overlying clay. The soil was placed and instrumented under controlled conditions in a 3.0m diameter by 3.0m deep concrete tank. The 60mm pile was dynamically driven using a pneumatically …

Thermally-induced ratcheting behaviour of laterally-loaded reinforced concrete energy piles in sand
An energy pile is an energy geostructure that has been increasingly used in practice for supporting and reducing carbon emissions from buildings or other infrastructure. It is subjected to vertical loading from the self-weight of the superstructure above, possibly horizontal loading due to pile …

Thermo-Mechanical Behavior of Energy Piles: Full-Scale Field Testing and Numerical Modeling
Energy piles are deep foundation elements designed to utilize near-surface geothermal energy, while at the same time serve as foundations for buildings. The use of energy piles for geothermal heat exchange has been steadily increasing during the last decade, yet there are still pending questions on …

Use of thermo-active piling for slope stabilisation
… and goods. A novel method, namely thermo-active pile row, was conceived to simultaneously increase the engineering performance of road embankments against slope failure and reduce the formation of ice.<br/><br/>In this thesis, the geotechnical implications of converting a row of traditional …

Tunnelling Effects on Bored Piles in Clay
… during tunnelling; this propagates through the soil to the foundations of buildings and infrastructure close to and above the tunnel. The interaction between these movements and the foundations is important for assessing movements and any subsequent damage to the overlying structures. Research …
