摘要
三峡船闸采用双线五级连续型式,船闸规模大、水头高,闸室有效尺寸280m×34m×5m(长×宽×槛上最小水深),上游水位变幅135～175m,下游水位变幅62.0～73.8m,设计总水头113m,最大通航流量56700m3/s,可通行万吨级船队,是目前世界上规模最大、总设计水头最高的船闸。自20世纪50年代开始进行设计研究,1994年4月开工,2003年6月建成并投入试通航。三峡船闸的建成投产,是多门类、多学科技术综合研究和运用的结果,三峡船闸一系列关键技术的研究解决,使船闸技术在多个方面取得了突破和创新。
The Three Gorges Project（TGP） on the Yangtze River is the largest water resources project in the world. The ship lock of the TGP is schemed as a double-way and five-step continuous ship locks; it has the characteristic of large size and high water head; and the valid size of single-step lock is 280 m×34 m×5 m （lengthxwidthx minimum water depth）. The ship lock of the TGP is the largest shiplock with highest design total water head in the world. The water level changes range within 135 - 175 m in up-stream, and within 62.0 - 73.8 m in down-stream. The design total water head is 113 m and maximum navigation discharge is 56 700 m^3/s, through which ten-thousand-ton fleet can pass; and the annual one-way passage capacity is fifteen million tons. The design and research of the TGP initiated in 1950s; it was been construction commencement in April, 1994, and it began tried navigation in June 2003. The ship lock of the TGP putting into operation is the synthetical research and applying consequence of many kinds of science and technology. Many technologies about the ship lock are acquired innovation and broke through by a series of science researches.
