Preventing foundation vibration due to train movement
Preventing foundation vibration due to train movement
(OP)
I'm designing a small (3.5m x 5m) residential slab-on-ground for an addition to a house near an urban train line, which is subjected to vibration. The house is about 100m from the vibration source and will be supporting single storey brick veneer construction.
I'm curious to know if there is a crude way of trying to isolate (or reduce) the slab from the vibration. If the slab was a raft slab with perimeter edge beams (say 400mm deep) and 1 transverse internal beam (through the centre), could I place high-density polystrene beside the raft ribs to try and isolate the slab from the ground movements and possibly under the slab to? Or, is a post and beam floor system on isolated piers more suitable as there is less area of footing exposed to the vibration and possibly less subsequent vibration. Due to a low construction budget there is no scope for sophisticated rubber isolation pads!
Any help would be appreciated.

If you want to do something positive, you could excavate an interceptor ditch between the structure and the track and fill it with gravel...this will create a discontinuous path for the vibration.
