Here is a picture of the twisted dam......
GoogleEarth of the Three Gorges dam and a nearby bridge. The bridge pic is to verify whether there is any distortion from the satellite imagery. As you can see, the bridge lines up with my yellow contrast line. The dam, however, is another matter. Its kinda ripply... And these images predate the current flood situation. If that dam goes...

Google Earth is using the pre-construction topography and warping the dam to fit that topographic base. If you pan around, you can see that the water behind the dam is "mounded" in places. Incidentally, I believe the Three Gorges Dam is upstream from the dam in your photo.

The issue is the dam really is in danger of collapsing...
I beliebe that you are wrong, because the chinese government has admitted that the dam has buckled in places...

i saw this report a couple of days ago


there's a forbes article that's saying the same, they've flooded a lot of land to try and release some pressure, fox is questioning integrity of the damn but they are the only major 'news' source claiming this so far

I saw an interview with an engineer that was invited to China during the early stages of construction, and he had serious concerns then. Basically it is not anchored into the bedrock, but merely sitting on it. The water can simply push the structure, which apparently is what is happening. The real question is how much movement is within design limits or reaches the failure point.

How the fuck do you build a dam without anchoring it into the bedrock? I'm no engineer but I do know enough about how things are built to know that you don't build something like a dam without anchoring it.

I've been hearing about the flooding and the risk of this dam collapsing for a long time now. I think China In Focus has been talking about it for 2 weeks.

How many projects did we let China do on infrastructure projects in this country?

For comparison, the current flood flows into the Three Gorges reservoir are 50-60,000 cubic meters per second. The mean flow rate of the Mississippi at Baton Rouge is 12,400 cubic meters/sec. The maximum flood flow on the Mississippi was ~30,000 cubic meters/sec.

Uh Oh! They are really going to be in a pickle if that sucker lets go.

I remember back to when it was been planned for, then built. Lot of outcry over forced relocations, and the environmental damage with all the abandoned mines and industrial zones, yikes. Outside pros were warning you can't make that kind of dam with that kind of river, and pointed to examples. The Chinese said no worries, we're better at math and engineering than you people, we got this. Uh, ok. Those pics do not look reassuring.

Tens, maybe hundreds of millions of Chinese are going to die if they were wrong. Could be the largest man made disaster in the history of civilization. I hate the CCP, but I'd prefer not to see Chinese people suffer horribly for the hubris of their leaders. Maybe securing/preventing looming disasters like that should be their focus, instead of invading and annexing outside territories under the fiction of 'indisputable sovereignty.' That volume of water looks a lot more like a threat to China than Filipino fisherman trying to feed their families by fishing in Filipino waters.

Must not have been able to steal the IP for making good dam.

Holy crab, if that's true that's simply insane. China has a long tradition of shoddy safety and building quality standards; remember those Tianjing port explosions about five years ago now for example? Also they've had elevated high speed train tracks collapse - apparently due to lack of rebar in the concrete... how's that for totally not-obvious corporate thievery and corruption?

And internet-famously, entire highrise buildings toppling and falling over on their side spontaneously and so on; "hilariously" also due to lack of anchoring/proper foundations, but considering the size of this damn dam this would take things to an entirely new level.

Scary, scary stuff! I hope the damn thing holds together so they can drain the reservoir later and repair, or if necessary, tear the mother down and rebuild. It would mean a colossal increase in coal powerplant pollution to replace the loss of electrical power though - not what this planet needs right now!

(You'd think you would build any dam strong enough so it survives water cresting it and pouring over the top. Anything less simply seems dam irresponsible to me!)

Like you said, if they make it through this flood season, they should open the flood gates and drain it. No way if those pictures are correct, that the damn will last more than a few years.

JediYoda's picture is not the Three Gorges Dam but a different dam about 38 km down river from the Three Gorges Dam.

This is the Three Gorges Dam:

Funny, because the Corps of Engineers here, built a damn on top of caverns ect. They backfilled with all kinds of debris.

I hope it is not true, I have no idea what kinda of damage it might result but there are many millions of people living after that dam.
