Centrifuge Tests on Rock-Socketed Piles: Effect of Socket Roughness on Shaft Resistance
J.G. Gutiérrez-Ch, G. Song, Heron, C.M., Marshall, A., Jimenez, R. Abstract 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 other factors, such as the degree of socket roughness, that […]

Different approaches have been proposed to model rock creep behaviour; however, many cannot reproduce tertiary creep (i.e., accelerating strain rates leading to rock failure). In this work, the distinct […]
A DEM-Based Factor to Design Rock-Socketed Piles Considering Socket Roughness
J.G. Gutiérrez-Ch, S. Senent, S. Melentijevic, R. Jimenez Abstract The Distinct Element Method (DEM) has gained recent attention to study geotechnical designs with rock-concrete or rock–rock interfaces, such as rock-socketed piles. In this work, 3D DEM models with non-standard contacts laws (the Smooth-Joint and Flat-Joint contact models) are proposed to analyze the response of axially loaded rock-socketed piles […]
