Quoted: What a total piece of garbage that construction is. It's individual linked concrete blocks. It's not anchored to the bedrock in any way - just resting on it. The comparison of the satellite photos a while ago and more recently shows exactly what you'd expect - the blocks are shifting independently from each other.

Quoted: Why do people think the cables are structural? https://cdn.britannica.com/20/119620-050-AC901996/Yichang-Three-Gorges-Dam-Yangtze-River-China.jpg View Quote Any idea what they’re for? If I had to guess without looking for more pics etc (and assuming it’s not the worlds worst choice for power line runs), I’d say they were a deterrent for incoming aircraft or missiles. Kind of like the cages around some tanks and apcs that cause RPGs to detonate early, before they make contact with the armored hull. |

Quoted: IIRC it'd take nothing less than a hydrogen bomb to crack it. View Quote No. A large conventional explosion, a few feet below the water surface next to the upstream side of the dam, would do it. Dams are not designed to withstand explosions. It is not their function. They are designed to withstand static hydraulic forces, and in seismic zones they are designed to withstand EQ forces. Neither of these mimic explosions. |

I hope there aren't any fresh water mussels downstream from that dam
if there are, we need dana on the job |

Quoted: Aren't dams better when placed at the narrow end of a canyon? That thing is so long it must be a challenge under any circumstances. View Quote The length of a dam is not really important. It feels the same hydraulic force everywhere along the length. Far more important is the design, foundation, and construction quality. China is also highly seismic, so that's a risk factor too. |

The Google Earth image looked "off" to me.
Zoomed in, and it looked even more off. Clicked in the right place, and this popped up: Attached File This is NOT a current photo of the dam. You have to turn off a lot of the Google Earth crap to see the actual photo. This is the current photo: Attached File Not quite a straight looking as the model, but nothing like that distorted photos. |

Quoted: Is any other dam in the world using cables externally as a structural component? View Quote I have seen a bunch of dams and I have never seen restraining cables on any of them. That said, I'm not willing to say that those are restraining cables. BTW, there are no cables capable of restraining the mass of the dam and the water behind it. It is impossible. The mass is bigly. |
|
Quoted: just out of curiosity.. could the excess weight of the overflow water increase the chance of an earthquake near the dam? View Quote Yes, there are examples of reservoir-induced seismicity. Usually, the EQs are relatively small. I am not aware of any major EQs caused by reservoirs. Theoretically it could happen, I suppose. |

I remember reading an article back in the nineties, regarding three gorges dam as being poorly designed and constructed. As was previously stated the dam is only blocks set upon ground and not anchored to any bedrock foundation. Also the dam walls have an earthen center and not
a solid concrete pour as western conventional design. If the dam fails aren’t the Chi-Com’s just likely to use a military action to distract its population from a failure of the nation’s all powerful central government? If this premise is valid it’s better for the dam to hold. Even if China could loose at third of it’s population? |

Assuming the quality and engineering is ten time the China norm, that damn should collapse within the next few years.
They usually build shit that starts to fall apart in only two or three years. |

It'd be a little damp downriver from that thing is all I know, and I'm kinda just guessing at that.

Quoted: Due to China's brainwashing, there isn't some secret population that actually likes us. At least in Iran, there are pro-Western folks. This dam failure could be the thing that actually takes down the Chinese regime. Their explosive economic trajectory is what kept them in power. This would devastate them, but could topple the regime. However, they, as a population, may be too far gone. What would replace the government? Taiwan stepping in to assist in governing would be cool, but also a pipe dream. View Quote if the Three Gorges dam failed, the Chinese government would lie and say the US dropped a PGM from a stealth bomber to make it fail. They'd turn their population against us. Win-win-win-win for CCP; they get to shift blame, make their population hate us more, have an excuse to cut the US off from electronic goods made there, and have a cover story casus belli for war against the USA. |

Kind of like the cages around some tanks and apcs that cause RPGs to detonate early, before they make contact with the armored hull. View Quote I think they are power lines. Each ganged pair of cables are in groups of three, which makes sense for 3 phase output from the turbines. You can see the insulators attached to the dam side and the low tension wires feeding the high tension run. |

Quoted: just out of curiosity.. could the excess weight of the overflow water increase the chance of an earthquake near the dam? View Quote If enough of the dam breaks at one time and drains the lake fast enough, the rocks under all that weight of the water will shoot into outer space once freed. |

In the late 50's/early 60's the Chinese built the damn on the Tigris River above Mosul, Iraq.
Iraq has spent the last 20 years trying to stabilize it. |

From a physics stand point I would love to see it fail, from a plane at a few 1000 feet. From a loss of life standpoint I hope it never does.
Or if it does they see it coming a few weeks before it happens so they can get everyone to higher ground. |

Quoted: Biggest concrete dam in the world. A failure would be no joke. View Quote Not a solid concrete dam like Hoover Dam. It's an earth-filled concrete shell. And one of the problems is that during construction there were chambers that had been filled and the dirt compacted which had all the dirt wash away. Three Gorges has serious problems if water is getting into the structure and flowing through the dam to wash away the earthen fill. The structure is a gravity dam which depends on the weight of the dam to hold it in place. If fill material is washing away the dam is losing weight and can reach a point where high water behind the dam will overpower the force of gravity to keep the dam in place and the water in check. There are reports that indicate that "the dam is warping", which would indicate that part of the dam is unable to hold back the flood-swollen river, likely due to material loss. In essence a slow-motion collapse phase of the Three Gorges Dam has already started. How quickly will it move on to a full speed collapse is the question and can China take any action to stop the erosion of fill to prevent a dam collapse? |

Show me a DAM designed to survive a 100 year storm and expect its first test to be a 1,000 year storm.

Quoted: Wow, if that goes, it will be a massive black eye to China, both internally and globally. Of course this would mean they’d need to flex and Taiwan is likely the target for that distraction. View Quote If their business drops off because of the world being pissed at them because of COVID that will definitely happen. |

if the whole thing collapses they'll surely claim that an unescorted group of US military service members took a tour there a few days before........

If those aren't shopped that is pretty scarry. I'm surprised it hasn't collapsed already. |

Quoted: In the late 50's/early 60's the Chinese built the damn on the Tigris River above Mosul, Iraq. Iraq has spent the last 20 years trying to stabilize it. View Quote ?? The Mosul dam was designed and built by the Germans in the 1980s, and the foundation issues were known at the time. The foundation is on chalk, so part of the dam design was a continuous grouting operation where grout is injected into the ground to fill the gaps left by the dissolving chalk. It's a decent enough solution IF you're in a stable country, which iraq was at that point in time. After saddam fell, the grouting operations were hit or miss, and they completely stopped when Isis took mosul - but the US has been in there providing support to ensure the continued grouting and stability of the dam. |
