Three Gorges Dam


The Three Gorge DamThe Three Gorges Dam site is 27 miles upstream from Yichang City proper, at Sandouping Town, 38km upstream from the Gezhouba Dam Lock, inside the third of the Three Gorges. It is planned to be by far the largest hydroelectric project in the world. The Project calls for the construction of a concrete dam, a hydroelectric power plant and a series of locks just below the scenic Three Gorges region.

The project is designed to be built in three phases and was scheduled for completion in year 2009. Upon arrival at Sandouping, passengers will take a bus across the Three Gorges Bridge, which leads toward the top of Three Gorges Project the hill for a birds-eye view of the construction from the observation deck.


History of the Three Gorges Dam

It is 75 years since Dr.SunYat-sen first proposed to launch the Project. Thanks to several decades of extensive scientific research and international cooperation by numerous scientists, scholars and experts of several generations, the extremely complex engineering poser for the construction of the Three Gorges Project (TGP) Yichangwas finally resolved. These studies provided the scientific basis whereby the National People's Congress passed "The Resolution for the Construction of the Three Gorges Project on the Yangtze River".

The project is designed to be built in three phases and was scheduled for completion in year 2009. Upon arrival at Sandouping, passengers will take a bus across the Three Gorges Bridge, which leads toward the top of Three Gorges Project the hill for a birds-eye view of the construction from the observation deck.

The Three Gorges Dam Project, which is the world largest water and power project, was kicked off on December 14,1994. The total construction period will be 17 years.

Selection Of The Site

Sandouping, 7 km from the entrance of Xiling Gorge at the lower reaches of the Yangtze River, was selected as the site of the Three Gorges Dam in 1959. The river here is much bigger than it is in other area. There is a small island named Zhongbaodao in the middle of this part of the river. It is the best choice of the site for the dam.

Three Gorges DamThe 1st Phase Of The Construction: 1993 - Nov.1997

The planning of the project was started in 1993. The actual building of the Dam started on 14 Dec. 1994. ZhongbaoIsland was used to build dyke A to dam the river water and to connect the right bank with the other dyke. In order to build the main part of the Dam and the diversion channel afterwards, foundation work B and foundation work C which is long and thin were built in the dry riverbed. At the same time, channel construction such as Lock D started.


Why to Built the Three Gorges Dam?

The Three Gorges Dam is the world’s largest power producing facility, and the world’s largest hydroelectric dam. There were many reasons for building the dam due to its history and other causes. This article will investigate some of these.

The Three gorges dam was built across the Yangtze River to control the amount of water allowed through. This created a massive artificial lake which has become an international tourist attraction. The construction of a dam on the Yangtze River had been considered since 1919, but the Civil war and Cultural Revolution delayed the project until fairly recently.

FloodingThree Gorges DamOne of the main reasons that the Three Gorges dam was built was to prevent flooding further downstream. The need for a dam was highlighted in 1954 when people were killed as a result of flooding of the Yangtze River.

Power Generation

Another reason why the Three Gorges Dam was constructed was to generate electricity. There are several generators within the dam which use the potential energy stored in the water, to generate electricity.

Environmental Impact

The dam has been designed to impact the environment as little as possible. It has meant that some ancient artifacts were lost, or are no longer accessible. However, it is stated that the impact on the environment is very small.

Visiting the Dam

The Dam isn’t just designed to save lives and generate electricity, but it is also a very popular tourist attraction. As it is the world’s largest hydroelectric dam it attracts thousands of tourists every year.


Freatures of the Three Gorges Dam

Three Gorges DamThree Gorges Dam  is situated at the upstream of Sandouping, Yichang City, Hubei peovince, 38km away from the Gezhou Dam at the downstream. Three Gorges dam has broken the world record for annual hydroelectric power production.The dam site is at Sanduoping,Yichang City, Hubei province. The total catchment area is about 1,000,000 square meters and there is 451,000,000,000 cubic meters of average annual runoff.

At the location of the Sandouping dam site, the river valley is relatively open and broad, with a small islet known as Zhoubaodao in the river, which is favorable for a river diversion scheme with phased construction. As regards communications, there is a railway to Yichang and a waterway to the dam site. A 26 km-long expressway has also been constructed from Yichang to the dam site. The bedrock at the dam site is sound, intact granite with a compressive strength of 100 developed. The rock mass has only very slight permeability.


Highlights of the Dam

The main elements of the project are the dam, two power plants, and the navigation facilities. The spillway dam section is in the center of the river channel, that is, on the original main river course, while the intake and non-overflow sections are Three Gorges Damarranged on each side. The powerhouses are to be located at the toe of the intake section. The navigation structures are on the left bank.The structure of the project are : Spillway , Left Powerhouse,Right Powerhouse,Ship lift,Temporary Ship lock,Permanent Ship lock,Dam Site. Since the project kicked off December 14,1994, it has attracted the world’s attention on it. More and more tourists are coming to see the world’s largest water conservancy project. Most passengers just come for enjoying watching this experience and the boat feels and looks something like a toy ship in the hands of a child-in the bathtub during the whole process. 

The world's largest water conservancy project with the biggest flood-control capability

The total storage capacity of the reservoir is 39.3 billion m3 ,of which 22.15 m3 is for flood control. After the completion of the TGP,The flood -discharging capacity of the Yangtze river would be 27,000 to 33,000 m3 /s,thus the floods from the upstream reaches of the Yangtze River could be controlled and the middle and lower reaches of the river,especially in Jinjiang reaches could be regulated or relieved.

The world's largest hydropower station

The total installed capacity of the Three Gorges Hydropower Station is 18,200 MW with an annual electricity output of 84.68 billion KW/h.

The world's largest water conservancy project with the world's largest project building scale

The total length of the dam axis is 2309.37 meters. The spillway section, which is located in the middle of the river course,is 483 meters long in total.There are 26 sets of turbine generator units in total, 700 MW for each.The shiplock is schemed out as a double-way and five-step lock.It is the world's largest water conservancy project with the world's largest project building scale.


How to Get to Three Gorges Dam?

The dam site is 27 miles upstream from YichangCity proper, at SandoupingTown, 38km upstream from the Gezhouba Dam Lock. It is very convinient to get there by ship from the cities along yangtze.

By Ship:

Most of the ships sail between Chongqing and Yichang, Shashi or Shanghai will stop here for an one-hour shore excursion. The avalibale luxury ships can be checked in the column of Yangtze Cruise.

By Bus:

There is an express way conecting the dam site with yichang. 
Travellers can take buses from Yichang to the Dam Site.
