Buckling of rock-socketed piles embedded in soft soils is intensively explored by utilizing three dimensional Finite-Element model in this paper. For pile-soil systems with a wide range of values of geometric parameters and material properties, the critical buckling load and buckling mode are obtained, and compared with the results based on Winkler foundation model. The simulation results show that the exact critical buckling load is a little bigger than that based on Winkler foundation model. The effect of rock-socketed ratio on the critical buckling load with three types of constrains is also investigated. With increasing rock-socketed ratio, the critical buckling load increases dramatically. The obtained results are useful to optimize the design of the pile-soil system against buckling in geoengineering applications.
