The Fushan Dam ( Chinese 浮山 堰 , Pinyin fúshān yàn ) on the Huai River (also: Hueihe, Huihe) in China was a dam that was built for war purposes in 516 and shortly afterwards destroyed by floods, killing 10,000 people perished.
Building
The Fushan Dam was built in 516 by Emperor Liang 150 km northeast of Nanjing in what is now Jiangsu Province to fight the Wei Kingdom and the garrison town of Shouyang. The dam was the largest that existed at the time. According to old records, the dam was 48 m high, 4500 m long, 108 m at the top of the dam and 336 m wide at the base. This results in slope inclinations of 1: 2.375 and a bulk volume of two million m³. The dam had two flood reliefs , but they were not efficient enough.
According to current knowledge, the dam was only 30 to 32 m high. That was enough to cover a storage area of 6700 km² and to have a storage volume of 10 billion cubic meters, making it the second largest in the world after the Volta reservoir .
purpose
At that time “war with water” was often waged in China. Dams were built to flood enemy cities or armies or, as in the case of the Fushan Dam, to cut passages.
fracture
Four months after the completion of the dam was at a high water flooded so that it broke. A large tidal wave caused up to 10,000 people to be killed downstream.
today
Remnants of the dam can still be seen at the village of Tonghe. During excavations in the 1950s, iron parts, bricks and arrows from the construction period were discovered.
