Journal Article
Gutiérrez-Ch, J. G., Song, G., Heron, C. M., Marshall, A., & Jimenez, R. (2021). Centrifuge Tests on Rock-Socketed Piles: Effect of Socket Roughness on Shaft Resistance. Journal of Geotechnical and Geoenvironmental Engineering, 147(11), Article 04021125. https://doi.org/10.1061/%28ASCE%29GT.1943-5606.0002665

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.

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...
