Research on Stability of the Rock-Socketed Piles in a Landslide Control Project

In order to study the stability of rock-socketed piles in landslide control project, this paper took a practical engineering as example, employed the ANASYS software platform as the implementation tool to establish the finite element analysis model. In this analysis, the Drucker-Prager criterion was selected and several differentiated models were established to research the influence of different socketed depth on rock stability. The result indicates that when the embedding depth is constant, the deformation of rock is growing with the increasing of load. When entering into the plastic response, the crack eventually developed into plastic zone around the rock-socketed pile; the adverse effects of the bottom rock would be smaller complying with the deeper of the pillar embedding into the rock; the cost increases with depth of embedded part in practical engineering, according to this research, it is economical and reasonable to choose triple pile diameter as the embedded depth.
