The Three Gorges Water Conservancy and Hydropower Project is the largest water conservancy and hydropower project built since the founding of New China 2. It is also recognized by countries around the world as the largest water conservancy project in human history. It embodies the efforts of generations and is a powerful witness and outstanding representative of China.
third-line water conservancy and hydropower project is located in Yichang City, Hubei Province. It is less than 40 kilometers away from another well-known water conservancy project in China - Gezhouba .
This project includes three parts, namely the main project, the tourist attractions and the eastern end of the reservoir.
How big is the Three Gorges Dam ? Its total investment is nearly 95.5 billion yuan, with a total length of nearly 3.4 kilometers, and the height of the dam top reaches 185 meters.
Due to the huge construction project volume, complex design and many considerations, the construction was not completed until May 20, 2006 after the start of construction on December 14, 1994.
What is the main function of the Three Gorges Dam? For this point, we need to find the answer from its name - water conservancy, hydropower.
The main body of the Sanxia Hydropower Station is 181 meters high, the normal water storage level reaches 175 meters, the total length of the dam exceeds 2.3 kilometers, and the investment is nearly 135.3 billion yuan.
This hydropower project has installed 32 hydropower units, with a single unit capacity of more than 700,000 kilowatts.
In other words, with the commissioning of the last unit and power generation, the total installed capacity of the Three Gorges Hydropower Project reached 22.4 million kilowatt-hours, and its annual power generation exceeded 100 billion kilowatt-hours in 2018.
To give a very specific example, the total annual power generation of the Three Gorges Hydropower Project is equivalent to the 11-year domestic electricity consumption in Beijing, which can generate huge economic benefits. According to incomplete estimates, the Three Gorges Project can contribute more than 12 trillion yuan to China every year.
But from the perspective of flood control, the effect of the Three Gorges Project is huge.
has a water storage capacity of 39.3 billion cubic meters, of which 22.1 billion cubic meters are specially used for flood regulation and application, which can reduce the peak flood flow up to 33,000 cubic meters per second, reaching the standard for defending against floods once in a thousand years. Such an important water conservancy and hydropower facilities,
, must play a crucial role in the production and life safety of the downstream people, as well as China's overall economic security.
This makes people worry, once the Three Gorges Dam is attacked by foreign countries, causing a dam collapse and 30.3 billion tons of water pour out, will it bring a catastrophe to China?
In fact, this worry is very normal and necessary.
As early as 1943, Germany and Britain were in full swing in World War II . At that time, Britain used artillery shells to destroy a dam in Germany, causing 400 million tons of water to pour out and more than 30,000 people to die.
Compared with this, the size of the Three Gorges Dam is undoubtedly huge. That is to say, once the Three Gorges Dam completely collapses, the disasters it brings will be very terrible.
However, everyone can be completely relieved that China has already taken careful precautions for this matter.
First of all, from a legal perspective, " International Law " clearly prohibits the act of destroying dams, because even if this act is used in war, the people will eventually be harmed. This anti-humane behavior is expressly prohibited by the whole world.
Secondly, the location of the Three Gorges Dam is very special. It is deep in the hinterland of China. If foreign weapons want to attack it, even if they launch an attack on the front line of China's coastal areas, for example, it will exceed 1,000 kilometers. Moreover, the surrounding mountainous terrain is very complex and basically impossible.
Finally, China had already considered this issue at the beginning of the Three Gorges Project construction, so military troops were stationed here all year round, and they maintained 24 hours of alert, duty, and patrol every day. The scope covers the road, underwater, water and air. It can be said that it is strictly guarding and has no loopholes.
Of course, if you want to make the Three Gorges Dam absolutely safe, it is important to rely on your own hard power.
In order to ensure the safety of the lives and property of hundreds of millions of people downstream of the dam, the Chinese government has made careful arrangements in military force defense, and at the beginning of the construction of Three Gorges , it has clearly stated that if any country dares to take attack actions, China will start a nuclear counterattack without mercy.
Specifically: First, in the dense jungle around the Three Gorges Dam, we deployed a large number of radar with a 24-hour boot-up realm, and deployed a large number of fighter jets for emergency takeoff and intercepting various types of aircraft.
, in particular, has established at least three layers of missile defense system , among which there are the famous Hongqi family products, and the defense coverage range is medium and long range, medium and high altitude, short range and ultra-low altitude, ensuring no blind spots.
Secondly, around the Three Gorges Dam, we have deployed many armed forces. These personnel have high training quality and are highly targeted. They are mainly to prevent the enemy's special combat operations organized by our Three Gorges Dam and ensure that they are eliminated in the cradle.
Finally, the people in the villages and towns where the Three Gorges Dam are located will take the initiative to "check out the gaps and fill in the gaps". As the saying goes, the people's eyes are bright. After the people participate in the patrol of the Three Gorges Dam, they will effectively discover those foreign spies with bad intentions to ensure the safety of the dam.
In fact, the Three Gorges Dam itself is also very solid. The dam adopts concrete gravity type, and the front edge of water barrier is already 2.3 kilometers long. When it was first built, the total concrete used reached an astonishing 17 million cubic meters.
The bottom of the dam body plays a key role in the safety of the dam is the bottom of the dam body. Because of the gravity construction method, the bottom of the dam body is completely integrated with the soil, riverbed, surrounding mountains and forests, and is leveraging each other to make it very strong.
The bottom thickness of the Three Gorges Dam reaches 126 meters, and the gates are all made of steel dozens of meters thick.
The general missile cannot be shaken at all. At most, conventional missiles only allow a few more small holes to the dam. Even if multiple hits cause gaps, it will not affect the entire dam body.
If the dam is completely broken, it must destroy the foundation at its bottom. To do this, you must use a large amount of nuclear weapon , and hit the key parts of the bottom of the dam several times in succession and multiple times.
is very difficult, and even if you can play it, it is difficult to achieve.
Even if it really reaches this point, China can still take measures to discharge floods in advance to maintain a low water level.
According to relevant data, the Three Gorges Dam can discharge floods at an average speed of 40,000 cubic meters per second while ensuring downstream safety. It can reach the flood limit water level in 7 days. If necessary, it can also be lowered by 130 meters, that is, an ultra-low water level of 10.3 billion cubic meters.
Further, if the worst happens, that is, the enemy continuously and accurately attacks the bottom of the Three Gorges Dam with large-equivalent nuclear weapons, and China has no early warning and no time for the Three Gorges Dam to discharge floods in advance, we still don’t have to worry too much.
The reason is: on the one hand, there are many mountains and rivers downstream of the Three Gorges Dam. The riverbeds of these rivers and the surrounding mountains form natural waterways. When the dam collapse occurs, these waterways will restrict the water flow, delay the time of its drainage, and win time for the transfer of personnel and property.
On the other hand, experiments have shown that even if the dam is completely collapsed and the water flows out in an instant, the scope of the disaster impact it brings is very limited.
Once someone on the Internet said that a defeat is very dangerous and can overwhelm the Central China Fair and cause hundreds of millions of deaths.
They also said that this accident will make Jiangxi, Hubei and other provinces and regions no longer suitable for people to live in, especially it will affect important cities such as Shanghai and Nanjing, causing serious losses to China's economy and industrial chain, and allowing China to retreat as a whole to the level of the 1970s and 1980s.
But in fact, we had already done many tests before the Three Gorges Dam was completed. Among them, there are not only multiple nuclear weapons blasting tests, but also related calculations.
Even in the worst case, the affected areas can only cover , Jingzhou, and the disaster is less than one-twentieth of the flood in 1954.
Of course, the above is the worst case. But China has now become a world power, and no one dares to take the blame for the world, hit stones with eggs, and dares to try to attack China's Three Gorges Dam.
Because they know that they will not only not succeed, but will also shoot themselves in the foot, triggering a full-scale nuclear war, and eventually they will perish.
