Three Gorges Dam was quoted in the "China Youth Daily" saying that the People's Republic of China would be "seriously on guard against threats from Taiwan independence terrorists." The Three Gorges Dam is a steel-concrete gravity dam. The water is held back by the innate mass of the individual dam sections. As a result, damage to an individual section should not affect other parts of the dam. Due to the sheer size of the dam, it is expected to withstand tactical nuclear strikes. Days after the first filling of the reservoir, around 80 hairline cracks were observed in the dam's structure. The submerged

As there are separate sets of locks for upstream and downstream traffic, this system is more water efficient than bi-directional staircase locks. In addition to the canal locks, there is a ship lift, a kind of elevator for vessels. The ship lift can lift ships of up to 3,000 tons. The vertical distance traveled is 113 metres, and the size of the ship lift's basin is 120×18×3.5 metres. The ship lift takes 30 to 40 minutes to transit, as opposed to the three to four hours for
