Tunnel–piled structure interaction: Numerical simulation of hybrid centrifuge tests (2021)
Journal Article

Tunnel excavation in urban areas causes ground movements that could damage existing nearby piled structures. Geotechnical centrifuge modelling has been widely used as a tool to study problems related to tunnelling activities and its interaction with...

Investigation of soil-pile-structure interaction induced by vertical loads and tunnelling (2021)
Journal Article

The response of pile groups and piled structures to vertical and tunnelling-induced loads is studied. A two-stage model is adopted that can efficiently consider external actions, greenfield tunnelling movements, superstructure stiffness, ultimate pil...

Centrifuge Tests on Rock-Socketed Piles: Effect of Socket Roughness on Shaft Resistance (2021)
Journal Article

Preliminary estimations of shaft resistance of rock-socketed piles are usually conducted using empirical formulations that relate to the uniaxial compressive strength (σc) of the weaker material involved (intact rock or pile). However, there are othe... Read More about Centrifuge Tests on Rock-Socketed Piles: Effect of Socket Roughness on Shaft Resistance.

Tunneling-Induced Deformation of Bare Frame Structures on Sand: Numerical Study of Building Deformations (2021)
Journal Article

The paper compares the performance of two Finite Element Method approaches in reproducing the response of bare frame structures to tunneling in dry dense sand. A fully coupled approach, in which the tunnel, frame and soil are accounted for, is comp...

Role of Footing Embedment on Tunnel–Foundation Interaction (2021)
Journal Article

This technical note investigates the effect of footing embedment depth on tunnel-structure interaction using geotechnical centrifuge testing. A two-story framed building on separate footings, either resting directly on the surface or embedded in the... Read More about Role of Footing Embedment on Tunnel–Foundation Interaction.

Centrifuge study on the use of protective walls to reduce tunnelling-induced damage of buildings (2021)
Journal Article

Tunnel excavation in urban areas causes ground movements that could damage existing nearby piled structures. In practice, to protect structures from tunnelling-induced damage, a stiff protective wall can be constructed between the tunnel and the adja...

Centrifuge application of fibre Bragg gratings: pile axial loads and wall bending moments (2021)
Journal Article

One challenge for geotechnical centrifuge testing of soil-structure interaction problems is the reliable measurement of induced structural strains/forces. This paper presents a novel application of fibre Bragg grating (FBG) sensors for strain measure...

Geotechnical Characterization of Fine-Grained Spoil Material from Surface Coal Mines (2021)
Journal Article

Coal mines produce large amounts of excavated waste soils, known as spoils. These materials can cover vast areas, are typically dumped in heaps without any treatment and are difficult to exploit for engineering purposes because of their significant v...

Cavity expansion-contraction based method for tunnel-soil-pile interaction in a unified clay and sand model: drained analysis (2021)
Journal Article

This paper proposes an analytical method based on drained solutions of cavity expansion and contraction in a unified clay and sand model to investigate tunnel-soil-pile interactions. Cavity expansion analyses are used to evaluate the effects of pile...
