IIRC the proper way to handle that is by anchoring the foundation of the building to the bedrock underneath the layers which can undergo liquefaction. That's done by means of drilling as deep as necessary to put the foundation and then adding pylons on which the building rests.
Depending on how deep the liquefaction-prone layers go, that's could be an option that's realistic only for a high rise.
- lmilcin 9y agoAnd how does that relate to Millennium tower which has already "sunk a foot and a half"? What if high rise building is anchored through all liquefaction-prone layers but the layers start to shift (they are on slight incline) when they get liquified? I am not expert but I can imagine it is possible that, if the structural support is long enough, just few inches of lateral movement may completely compromise the support.
- stale2002 9y agoBecause the millennium tower did NOT do the correct thing, and did not anchor it to bedrock. They would be having problems if they did it the right way.
- ummonk 9y agoOr you can design the building to float on the liquified soil. Either way works.
