Where is the Three Gorges Water Control Project?

The Three Gorges Water Control Project is located in Sandouping Town, Wuling District, Yichang City, Hubei Province.

The Three Gorges Hydropower Station, namely the Yangtze Three Gorges Water Control Project, is also called the Three Gorges Project. The Xilingxia reach of the Yangtze River in Yichang City, Hubei Province, China, and the Gezhouba Hydropower Station in the lower reaches form a cascade hydropower station.

The Three Gorges Hydropower Station is the largest hydropower station in the world and the largest construction project in China. However, many problems caused by it, such as immigration, environment and so on, have been accompanied by great controversy since the moment it started construction. The Three Gorges Hydropower Station has more than ten functions such as shipping, power generation and planting.

The Three Gorges Dam is mainly composed of water retaining and flood discharging main dam, power generation building, navigation structure and other buildings. The dam body is a concrete gravity dam with a dam axis of 2309.47 meters and a total length of 2335 meters. Dam crest elevation 185m, maximum dam height181m; Normal water level175m, with a total storage capacity of 39.3 billion cubic meters.

Main functions of the Three Gorges Water Control Project

1, flood control

Historically, floods occurred frequently in the upper reaches of the Yangtze River and its tributaries. Every time a catastrophic flood occurs, the Jingzhou section of the Yangtze River (Jingjiang River) below Yichang should take flood diversion measures to flood the countryside and farmland to ensure the safety of Wuhan.

After the completion of the Three Gorges Project, the storage capacity provided by its huge storage capacity will enable the downstream Jingjiang area to resist the once-in-a-century flood, and also contribute to the governance of Dongting Lake and the comprehensive restoration of Jingjiang levee.

Step 2 generate electricity

The economic benefits of the Three Gorges Project are mainly reflected in power generation. The project is a giant power supply point in the middle line of china xd East Power Transmission Project, and the generated power will be mainly sold to Hubei, Henan, Hunan, Jiangxi and Chongqing in Central China Power Grid, Shanghai, Jiangsu, Zhejiang and Anhui in East China Power Grid and Guangdong in South China Power Grid, which can alleviate the tight power supply situation in China.

3. Ships

Before the impoundment of the Three Gorges, the annual one-way traffic volume of Chuanjiang River was only 6.5438+million tons, and 10,000-ton ships could not reach Chongqing at all. The Three Gorges Project ended the history that "Sichuan has never sailed at night since ancient times". Through several impoundments of the Three Gorges, the navigation conditions of the Sichuan River have been improved day by day. In 2009, the freight volume passing through the Three Gorges Dam was about 70 million tons.
