Human beings always correct their behavior in mistakes, the same is true for engineering construction, but every mistake will pay a huge price, let us think bitterly, so each generation of engineers will do things will be extremely rigorous, summarize the mistakes of predecessors, make changes, although it sounds a little cautious, but it is these mistakes that push us forward, let's take a look at the world's top ten famous engineering disasters, man-made hell disasters.
It happened in 2003, and the protagonist of the matter was several astronauts, who were carrying the space shuttle Columbia, and when they were ready to fly into space, there was an accident, that is, their insulation layer was not processed, a piece of material fell off, and after falling off, it hit the shell of the aircraft and produced a crack, which directly interfered with the space shuttle's return capsule and caused the space shuttle to disintegrate in the air, which led to the disaster.
This happened in 2000, and the protagonist of the matter was an airline flight, Flight 4590, which took off from the airport in Paris, France, but had an accident before it was fully taken off, because there was a sharp metal object on the runway, and the tire scratched the metal object when the plane was about to take off, which made the take-off frame of the aircraft unable to be fully recovered, resulting in the crash of the plane.
The Cherbyl disaster is the most profound thing, occurred in 86, when the Soviet Union has not yet disbanded, and the Soviet Union at that time after the disaster still wanted to try to hide, but did not expect that the impact of the nuclear power plant leakage is too large, triggered a large number of explosions, the local ecological impact is also very serious, as for scientists estimate, the nuclear radiation here to dissipate, about a few thousand years, is one of the world's ten most famous engineering disasters.
It happened in '86, and the protagonist of the matter is the Space Shuttle Challenger, he is one of the first to fly into space, so there are many technical imperfections, such as this time they had a problem at launch, their power system did not fully play a role, until the space shuttle disintegrated in the air, all the people on the plane were killed.
It happened in '81, and the location of the matter was a hotel in the United States, the name of this hotel is called the Hyatt Hotel, and the incident happened in Kansas City, this hotel was originally several floors, his second time there was a collapse, so that the entire building was destroyed, in fact, this is still part, all the people on the first floor died a total of 114 people, and afterwards according to the investigation is because the corridor of the building is not designed properly and caused the collapse.
It happened in 1944, and the specific place was in the middle of Ohio, the United States, what happened was a natural gas leak, at that time they did not know how to save natural gas, so they stored natural gas on the ground, unexpectedly because of the temperature of the natural gas leak after a series of fires and explosions, resulting in 130 deaths, since then they changed the storage method.
Human beings always make continuous attempts in engineering, such as the suspension bridge in the Tacoma Strait, he is one of them, he is the first rope bridge in Washington state, and one of the longest suspension bridges in the world, but because of the unreasonable design, less than a few months after his opening, the bridge collapsed, and according to the accident investigation, they found that the design of the suspension elastic structure connecting the bridge was unreasonable.
In the past many countries have always wanted to develop airships, they have never given up, until the Hindenburg air disaster, they realized that the airship is not possible in the real sense, this airship is flying from Frankfurt, Germany to New Jersey, in the process of flight, because of the spark generated by the static electricity of the generator and the hydrogen reaction in the airship, a large explosion occurred, and all the personnel on the aircraft were killed.
The St. Francis Dam was originally a large dam in Los Angeles, it was completed in 1926, this dam is far from the residential area, in a canyon 64 kilometers southwest of the residential area, at that time only considered the reason for the distance, did not take into account the geographical reasons, in less than two years after the construction, the dam collapsed, the accident caused the death of more than 600 people in the surrounding villages, is one of the world's ten most famous engineering disasters.
The time of the sinking of the Titanic is naturally needless to say, it can be regarded as the biggest disaster in human history, when the collection of the Titanic was only considered as a yacht, its volume is the greatest, the interior is the most luxurious, and they want to call it unsinkable because of the huge collection, but what they did not expect was that on his first voyage, it hit an iceberg, and the number of people killed reached 1517 people, and the cause of the accident, the first is because of the materials used to make this ship, Another point is that its sealed cabin design is unreasonable.
