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.

Centrifuge study on the use of protective walls to reduce tunnelling-induced damage of buildings (2021)
Journal Article
Song, G., & Marshall, A. M. (2021). Centrifuge study on the use of protective walls to reduce tunnelling-induced damage of buildings. Tunnelling and Underground Space Technology, 115, Article 104064. https://doi.org/10.1016/j.tust.2021.104064

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...
