Boring effect on soil in Plaxis 2D

Hi,

It depends on how you construct your bored pile.

1. drill a hole and then fill it up with concrete
2. bore a hole with support fluid (bentonite, for instance), then fill up with concrete
3. pressure driven injection piles
4. .....

Apart from the 1st option, which is just switch off the soil/rock and then fill it with concrete, there is an intermediate step in which a pressure through a user-defined pore pressure is applied. Whether this pressure is low causing relaxation or high causing expansion depends on the method used.

With kind regards,
