If buildings in Venice are crumbling at the foundation because of the waves from speed boats, why don't they build deep metro below the lagoon to move people and goods within Venice and to and from the mainland and completely ban boats?
>>2059050Because the foundation of the city is mud, not rock. It's all river and glacial sediment projecting into the Adriatic basin.The buildings themselves are built on tree-trunks hammered into the mud until resistance was too high to hammer them farther. They are not sitting on bedrock or anything, they are basically free-floating in the mud.https://www.bbc.com/future/article/20250324-the-ancient-forest-that-supports-veniceMaybe you could dig a metro deep enough to actually put it in the bedrock? I'm not familiar with the specific geology of the area. But if you systematically disturb the mud that all these buildings are floating on (for example, from vibrations and subsidence due to the tunnel), then you are going to destroy whole strips of the city. And never mind the destruction from digging out the stations.Also, has anyone actually built metro stations under water? I mean, maybe it has happened somewhere in the world, but it's not exactly an easy problem building the cofferdams, draining and hollowing them them out, and keeping the work area from flooding as you dig to meet the tunnel.
Why don't they just line the channel with concrete?
>>2059103if all the houses are sinking, what makes you think a open-faced concrete box wouldn't?
Venice is a meme town. It’s just a giant swampy tourist trap with old buildings in it. The only reason it exists is because a thousand years ago or so the locals would save themselves in that swamp from the hordes of invaders or something. Today it’s just a quirky but dangerous museum. People shouldn’t be living there anyway. They should just evacuate anything of value and let the old buildings slowly sink and return to the sea. Keep the boat tours but don’t let people walk there due to danger.
>>2059308>People shouldn’t be living there anywayEvery year the population of Venice (the island portion) drops by 1,000. Within 50 years the permanent population will cease to exist.
>>2059055>I'm not familiar with the specific geology of the area.i don't know a ton but iirc when you have muddy places like that usually there isn't accessible bedrock and the mud is on top of gravel and soft stone>>2059308akshually it exists because a thousand years ago some rich bankers moved there because taxes were low and power projection onto it was minimal so they then started financing mercenaries and making bank basically being Medieval Blackwater
>>2059111What if you start digging into the bedrock using a TBM from the shore towards St. Mark's Square?
