The full name of Three Gorges project is Three Gorges multipurpose
water control project. The whole project includes a concrete gravitational
dam, a sluice gate, a latter dike hydroelectric power station, a perpetual
navigation ship lock and a ship lift. The building of the project
is made up of three parts the dam, the factory building and opening-navigation
building .The top of the dam is 3035 meters long and 185 meters high.
There're 26 machines, 14 on the left and 12 on the right. A small
wheel generating set has a front row capacity of 700,000kws. The total
installed capacity is 1,820 kW/h. Annual generated energy reaches
84.7 billion kW/H. The navigation building locates at the left bank,
including a double -lined and five -package consecutive ship lock
and a first -rate vertical ship -lift.
Three Gorges project will last for 18 years
of three periods. The First phase (1992-1997) lasted for five years.
Besides the preparation work, the chief project included first period
cofferdam, the beginning of the diversion channel, a concrete longitudinal
cofferdam and a temporary ship lock (120 meters high), the beginning
of a left bank perpetual ship lock, a lift and part of stone dam at
the left bank.
Now the first
phase has been finished after the Yangtze River was dammed in November
1997.The water level has been raised to 88 meters from the original
The finished diversion channel can support the maximum discharge
of 2,000 cubic meter per second. Therefore, the water transportation
and shipping on the Yangtze River wouldn't be affected a lot. It's
guaranteed that navigation is smooth during the building period.
The second phase
will last for six gears (1998--2003). The major task is to build
the second period of cofferdam and equipment and the settling of
the left bank station .At the same time, a perpetual special grade
ship lock and the construction of the ship lift are to be continued
and be scheduled to finish. In June 2003, the retained water in
the dam would be raised to 35 meters high and be stretched into
WanXan City along the Yangtze River. As a result of this, ZhangFei
Temple would be inundated and water would become steady and smooth,
so that those entire dangerous shoals could never be seen again
and there would be no difference between upstream and downstream
during the inner part of the River. The perpetual Navigation would
be accomplished and be put into practice; the first machine unit
on the left begins to generate electricity in the same year.
The six -year
Third phase (2003 -2009) is planed to continue the right -back dam
and the station. Besides, all the machine sets are to be fixed.
On the occasion, Three Gorges Reservoir would be a smooth -leveled
and valley -like reservoir with the length of 600 kilometers, the
width of 200 meters and the area of 1000km2. The average depth of
the water would increase 10 to 100 meters than now .The normal retaining
water level is 175 meters above sea level in winter; while on the
account of resisting blood in summer, the water lever is approximately
145 meters above sea level. After retaining, the front dam water
level is to be raised about 100 meters. Thus some landscapes and
places of interests would be under the influence. When the second
project is over, ZhangFei Temple would be flooded; in the year of
2006, the water would be increased to 156 meters and QuYuan Temple
in Zigui would be submerged; in 2009, the dam is to be completed.
Three yeas later, that's 2012, the final water level would reach
175 meters high. The actual raising of water is 110 meters. The
back water would trace back 650 kilometers to the boundaries of
Chongqing .The existing tourist spots can be preserved till the
end of the second phase in 2003. After the completion of the whole
project in 2009, 39 man-made and natural landscapes in the region
would be submerged entirely or partly, taking up 13% of all the
landscapes along the reservoir region. Because of their relative
high elevation, two regions, Wu Gorge and Qutang Gorge, just have
a increasing of water level of 80 meters. Moreover, the mountain
series and cliffs in both banks posses an elevation of hundreds
meters or even thousands. Except part of ancient plank roads and
dissolved holes, others wouldn't have a great change. In the west
sector of XiLing Gorge Region, only BingShuBaoJian Gorge and NiuGanMaFei
Gorge would be submerged. However, Yellow Gorge and Light Shadow
Gorge in eastern sector between the two dams would still exist.
So along the famous Three Gorges, Goddess peak would still stand
gracefully and Kui Gate still be grand. Although a few of the scenes
would disappear, about a hundred new landscapes would emerge owing
to the raising of backwater. BaiDi City and Shibaozai would become
BaiDi Island and ShiBao Island respectively. Many branches of Changjiang
River from a variety of tourist resources is waiting for us to cultivate
and utilize. Though the Yangtze River grand dam was damned, the
landscapes are still charming. Afterwards, the cruise ships along
the routine will be built lager and will be more smooth and comfortable.
The focus of the tourism will change, the tour lines will be varied
and the present structure will take a new look. Perhaps people will
not be worried about the merits or demerits of the upstream and
the downstream, nor will cruise company cover the price difference
in two situation .The Three Gorges dam centered golden tourist region
will become a splendid shining star on the Yangtze River.
