Jinanqiao Dam
The Jinanqiao Dam or Jin'anqiao Dam (, meaning "golden and peace bridge") is a concrete gravity dam on the Jinsha River  southeast of Lijiang City in Yunnan Province, China. The purpose of the dam is hydroelectric power production and flood control. Construction
The Jinanqiao project was approved in August 2003 and construction began in 2005. By December of that year, the river was diverted and the construction of the actual dam began in January 2006. By February 2007, the foundation had been excavated and concrete pouring began. In June 2010, the dam's first generator was operational, the last was commissioned in 2011. Design
The dam is a  tall and  long gravity dam composed of  of roller-compacted concrete. The dam's crest elevation is  above sea level and it withholds a  reservoir with a normal storage level of  ASL. Of the reservoir's storage,  is active or "useful". The dam's spillway consists of five  x  openings which have a maximum flood discharge capacity of . To prevent scouring, the dam has a stilling basin at the foot of the spillway. The dam's power station sits at its toe and adjacent to the spillway. It is  long,  wide and  high. Four penstocks with a  diameter feed the 4 x 600 MW Francis turbine-generators which can discharge up to  after generation. Each Francis runner has a  diameter. Because of high seismic activity in the area of the dam, special care was taken during design and construction to prepare the joints and foundation for sliding and tensile stress. Earthquake-resistant steel bars were installed in high-tensile areas, the construction joint was reduced to 2/3 its size and filled with non-woven fabrics along with the incorporation of a grouted joint between the dam and power plant.
