✦ Synopsis

A cavity expansion procedure for the simulation of pile driving is presented and assessed in this paper. The analysis uses a non-linear "nite-element model and the penetration of the pile into the soil is simulated by a radial opening of the soil around the pile. The case of a pile advanced by expansion will be compared to a similar pile subjected to computational driving (referred to, respectively, as &expanded' and &driven' piles for convenience). The state of stress and deformation, and the evolution of pore-water pressure in the soil will be monitored for the expanded and driven piles. Further computational driving will be applied to both cases and the pile response and soil resistance will be compared. The computational cost of advancing the pile by expansion will "nally be investigated.

The plugging mechanism of infinitely-long open-ended piles is examined using numerical simulation of the wave propagation inside the soil plug and pile. It is shown that the key parameters for the plugging mechanism are the pile radius, the shape of the impact load, the shear wave velocity of the so

## Abstract In situ measurements, carried out in deep excavations during construction, show that the installation of anchor piles to prevent uplift of the formation level slab leads to large deformations in the excavation support works. Currently, it is hardly possible to predict these installation
