三峡大坝位于长江三峡西陵峡中段的三斗坪镇,距宜昌市区44公里,且有宜昌至武汉、黄石的高速公路相连,是在建的当今世界上最大的水利枢纽工程。三峡工程全称为长江三峡水利枢纽工程。1992年4月3日,七届人大五次会议审议并通过了《关于兴建长江三峡工程决议》。1994年12月14日,三峡工程在前期准备的基础上正式开工。
三峡大坝主要由拦河大坝、电站厂房、通航建筑物等三大部分组成,大坝为混凝土重力坝,坝顶高程185米,总装机26台,单机容量为70万千瓦,总装机容量为1820千瓦,年发电量847亿度。工程动态总投资2350亿元。总工期17年(1993年正式开工,2009年全部建成)。工程竣工后,水库正常蓄水175米,具有防洪、发电、航运、旅游等多种综合效益。工程边施工、边开展旅游,浩大的施工现场和现代的施工手段、优美整洁的施工生活环境吸引了无数关心支持三峡工程建设的中外宾客。
目前,三峡大坝专门开辟了许多旅游参观景点,以便让来宾更好地、全面地了解这个举世瞩目的特大型工程,主要旅游景点有:坛子岭观景点、模型室、185平台、西陵长江大桥、导流明渠、大坝公园等景点。
三峡工程的兴建,会促进长江的综合治理和开发,也必将加快中国现代化建设进程。
The Dam Project is the biggest hydraulic engineering project in the world. The dam is located at Sandouping, the middle section of Xiling Gorge. The earth was broken in 1994. The project includes: the main work, power plant, flood discharge silt sluice, sand discharge get, a twin 5-step ship lock and a twin elevator for ships. It’s estimated the Project will cost 230,000 million U.S. dollars. The purposes of the Three Gorges Project are flood control, electricity generation improvement of navigation and water transference from the south to the north. The Dam will be 2,335 meters long, 18 meters wide, and its bottom will be 130 meters wide after completion. The water has risen 66 meters and will rise 40 more meters by 2009. This is at the dam site so it will rise 36 at the first gorge, 24 at the Wu Gorge and 12 at the western most gorge, thus forming a 600-kilometer long reservoir with a storage capacity of 3,990 million cubic meters after 2009. So, now is the time to come.
