夹山江水利枢纽设计 摘要 夹上江是我国大河流之一，其干流全长700公里，流域面积17400平方公里；楚河是夹上江的重要支流，流经夹上江的上下游地带，全长250公里，流域面积7200平方公里。楚河开发计划是配合夹上江而制定的。楚河楚峡水利枢纽就建立在楚河和夹上江汇流处的楚峡。 枢纽属一等工程，以防洪和发电为主，兼有航运等综合效益。其主要建筑物有：混凝土实心重力坝、引水建筑物、泄洪建筑物、放空建筑物、过坝建筑物和电站厂房等。 枢纽按千年一遇的设计，五千年一遇的洪水校核。水库正常蓄水位178.0米，设计洪水179.3米，校核洪水位180.13米。电站装机3台2.4千瓦，总装机72000千瓦。船闸可以保证80吨级驳船通航。 主体建筑物实体重力坝坝顶高程182.04米，最大坝高46.04米；泄洪采用表孔，共三孔，每孔宽12米，岩堰顶高程170.92米；放空采用深孔，设一孔，宽3.5米，高4米，底板高程151米；电站引水采用坝内压力钢管，钢管直径4.5米；电站厂房为坝后式。 本设计对枢纽的主体建筑物进行了认真的方案比选和详细的尺寸设计，并对所设计的建筑物进行了安全校核，保证建筑物的安全运行。同时对水电站和施工导流进行了简要的设计。 关键词：夹山江； 楚河； 水利枢纽； 大坝Abstract Jia Shan Jiang is one of Chinas largest river, the main stream length of 700 km, drainage area 17,400 km2; Chu Jia Shan Jiang River is a major tributary of the upper and lower river flows through the forest zone, length of 250 km, drainage area 7200 km2 . Chu Jia Shan Jiang is in Xiae with development plans drawn up. Chu Chu Xia Dam on the establishment of the Chu River and the confluence of the Chu Xia, Jiang Xia. ?Hub is a first-class engineering, flood control and power generation based, both shipping and other comprehensive benefits. The main buildings are: solid concrete gravity dam, diversion structures, flood the building, emptying buildings, power plants and other buildings and Dam. A return by the Millennium Projects design, five years return period flood check. Reservoir normal water level 178.0 m, 179.3 m Design flood, check flood level 180.13 meters. 3 sets of 2.4 kilowatts installed capacity of power plants, the total installed capacity of 72,000 kilowatts. Lock can ensure that 80-ton barge shipping. Dam crest elevation of the main building entity 182.04 m, maximum height of 46.04 m; discharge by surface hole, a total of three holes, each hole 12 meters wide rock weir crest elevation 170.92 m; emptying using deep hole, to set up a hole, wide 3.5 meters, 4 meters high, bottom elevation 151 meters; Power Station penstock diversion dam used, pipe diameter of 4.5 meters; power plant for the dam toe.
