Distinct-Element Method Simulations of Rock-Socketed Piles: Estimation of Side Shear Resistance Considering Socket Roughness
J.G. Gutiérrez-Ch, S. Melentijevic, S. Senent, R. Jimenez Abstract Rock-socketed piles are foundational elements designed to transmit large concentrated loads to stronger materials located at greater depths. The rock-socket side shear resistance is commonly estimated using empirical criteria as a percentage of the rock or concrete uniaxial compressive strength. However, this approach neglects the influence of other important aspects, such […]
Distinct element method simulations of rock-concrete interfaces under different boundary conditions
J.G. Gutiérrez-Ch, S. Senent, S. Melentijevic, R. Jimenez Abstract The shear behaviour of concrete-rock interfaces has been the aim of extensive research in geotechnical engineering applications such as rock socketed piles, rock bolts and concrete dam arch bridge foundations. Several experimental studies through direct shear tests have been conducted to evaluate the shear behaviour of rock-concrete interfaces under CNL (Constant Normal Load) and […]
DEM simulation of rock creep in tunnels using Rate Process Theory
J.G. Gutiérrez-Ch, S. Senent, P. Zeng , R. Jimenez Abstract The time-dependent (creep) behaviour of rocks affects the safety and stability of tunnels excavated in weak rocks and at great depths. Several theories have been proposed to simulate the creep deformation in rock; i.e., the progressive time-dependent damage that rocks (or other materials) exhibit under constant stress. However, most of these theories do […]

Rock shear creep modelling: DEM – Rate process theory approach
J.G. Gutiérrez-Ch, S. Senent, E.P. Graterol, P. Zeng , R. Jimenez Abstract Understanding the rock creep behavior is necessary to determine the long-term strength and safety of several geotechnical designs. There are several formulations to study the rock creep; however, most of them do not properly capture the tertiary creep. To overcome such limitation, model improvements have been made and new creep models (e.g., creep models […]
