Behavior of Rock Socketed Pile in Jointed and Weathered Rockmass Under Earthquake Loading
Rock socketed piles efficiently transfer the heavy loads from high-rise buildings, long-span bridges, and offshore structures to bearing strata. In the present study, A 3D finite element analysis of a rock socketed pile subjected to earthquake loading is carried out by PLAXIS 3D, and the rock socketed pile is embedded in a jointed rockmass and weathered rockmass. The pile material is modeled as linear elastic, whereas Mohr’s Coulomb and Hoek- Brown material models are used for the simulation of soil and rock. The acceleration-time history of the 1991 Uttarkashi earthquake is considered for the seismic analysis. The observations are recorded to understand the effect of dynamic loading on the displacement of socketed piles for different socket lengths. The effect of soil cover depth and socket length are also studied in the present work. The socket length considered is 3, 5, and 10 times the diameter of the pile. It is observed that the settlement of the rock socketed pile increases with an increase in weathering grade from W0 to W4. The settlement of the rock socketed pile is also dependent upon the GSI parameter of rockmass.
