Records of Three Gorges Dam
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.
The world's largest water conservancy project with the biggest project workload
The earth-rock excavation of the main structure of the project is 134 million m3 and the concrete placement is 27.94 million m3. The installation of reinforcing bar and metal structure is 463 thousand ton and 256.5 thousand ton respectively.
The world's largest water conservancy project with the biggest construction difficulty
the concrete placement of the TGP in 2000 is 5.4817 million m3, 550 thousands m3 for each month ,which created a new world record .It is the world's largest water conservancy project being built with the biggest construction difficulty.
The world's largest water conservancy project with the strongest flood-discharge capability in the world
The maximum flood -discharge capacity of the spillway is 102.5 thousands m3/s, which ranks the top one in the world.
The world's largest water conservancy project with the biggest and the most complicated shiplift in the world
The shiplift is designed as one stage vertical hoisting type with a maximum hoisting distance of 113 meters.the ship container of the shiplift is in a size of 120*18*3.5 m,capable of carrying 3,000 tons of passenger or cargo boat each time.It is the biggest and the most complicated shiplift in the world.
The world's largest water conservancy project with the world's largest and the most arduous resettlement
The total number of the migrants to be resettled of the reservoir area of the TGP may reach 1.13 million by the end, It is the largest and the most arduous resettlement project in the world.
