Drainage area of 3550 square kilometers. Shanxi Hydropower Station dam site is located in the main stream of the upstream segment of Feiyunjiang Wencheng County, Shanxi commune fish show near the village, to control the drainage area of 1529 square kilometers, 43.4% of the total drainage area.The water control project is a large-scale water control project, engineering, etc. Do not (1) type, the main task is to irrigation, flood control, power generation, the dead water level of 130.0 meters, the normal water level of 160.0 m, corresponding downstream water level is 51.14 meters, installed capacity of 170,000 kilowatts, the unit number 4. The hub of the main building (retaining structures) by five 100-year flood design, design flood level 163.58 m, the discharged volume of 4256.4, the downstream water level of 52.36 meters ; at two thousand one case of flood check, check flood level of 163.58 meters, the discharged volume of 4676.3, the downstream water level of 52.62 m. Dam height of 145.07 meters of masonry gravity dam, the dam axis is 540.0 meters long, flaring pier Bucket joint energy dissipation.The layout of the water diversion tunnel on the right bank, diameter 8.5 m, length of 350.0 meters, the diversion tunnel reinforcement inside and outside the ring bars mat ching 6Φ12/14 @ 80. The basic structure of the surge chamber type for a simple surge chamber, whose diameter is 25.2 m and a height of 12.15 meters. Penstock diameter 8.0 m, length of 180.0 meters, a wall thickness of 35.0 mm.Hydropower plant layout and cattle Creek exit the left side of the foot of the slope at the diversion type, their buildings are level two. Turbine Type HL -200 - LJ - 250, the maximum head of 109.89 m, a minimum head of 79.86 m, design head of 97.88 meters, design flow of 48.66. The main plant size is 45.92 × 20.0 × 36.823, and auxiliary plant size is 45.92 × 8.0.Vent empty without pressure type, imports at the top elevation of 49.0 meters, the bottom elevation of 43.5 meters, 5.5 meters in diameter. Diversion structures for the three -level, the choice of the whole section of the cofferdam method with the program of the diversion tunnel, diversion tunnel hole diameter of 8.0 m, length of 800.0 meters. Hydraulic steel gate selection of radial gate type, its size is 12.0 × 10.5.Key words: Shanxi Hydropower Station, masonry gravity dam, steel radial gate目录中文摘要 (I)Abstract (Ⅱ)第1章绪论 (1)1.1 引言 (1)1.2 设计背景 (1)第2章设计资料 (3)2.1 流域概况 (3)2.2 气象 (3)2.3 水文泥沙 (4)2.4 工程地质资料 (4)2.5 引水隧洞及厂房工程地质条件 (6)2.6 导流隧洞工程地质条件 (6)2.7 天然建筑材料 (7)第3章调洪演算 (8)3.1 洪水标准 (8)3.2 洪水调节计算 (8)第4章坝址、坝型选择 (10)4.1 坝轴线 (10)4.2 坝型 (10)第5章非溢流坝段 (11)5.1 坝顶高程 (11)5.2 坝底宽度 (11)5.3 坝顶高度 (13)5.4 坝体上下游坡率及折坡点高程 (13)5.5 坝顶宽度 (13)5.6 荷载作用及荷载组合 (14)5.7 各种工况下抗滑稳定分析 (19)5.8 各种工况下应力分析 (20)第6章溢流坝段 (22)6.1 溢流重力坝孔口设计 (22)6.2 溢流重力坝堰面设计 (24)6.3 消能防冲设计 (25)6.4 堰面水面线 (27)6.5 导水墙 (28)6.6 溢流坝顶结构尺寸 (29)6.7 荷载作用及荷载组合 (30)6.8 溢流坝段抗滑稳定分析 (36)6.9 各种工况下应力分析 (36)6.10 细部构造 (37)6.11 大坝地基处理 (39)第7章水电站引水建筑物 (40)7.1 引水隧洞 (40)7.2 进水口的布置和设计 (40)7.3 压力管道 (42)7.4 调压室 (43)7.5 洞身结构 (47)7.6 配筋计算 (53)第8章水电站厂房 (55)8.1 水轮机选型 (55)8.2 发电机型号 (58)8.3 主厂房高度 (58)8.4 主厂房长度 (61)8.5 主厂房及副厂房宽度 (62)第9章其他枢纽建筑物 (63)9.1 泄空洞 (63)9.2 导流建筑物 (64)第10章水工钢闸门设计 (67)10.1 闸门的布置 (67)10.2 闸门自重 (67)10.3 闸门的基本资料和结构布置 (67)10.4 结构计算 (69)10.5 启闭力的计算及启闭设备 (76)10.6 闸门支铰 (77)10.7 吊轴和吊耳板 (79)10.8 止水及埋件 (80)第11章枢纽工程量 (82)11.1 土石方开挖 (82)11.2 土石方填筑 (83)谢辞 (84)参考文献 (85)第1章绪论1.1 引言水能是可再生能源,地球表面以海洋为主体的水体,在太阳能的作用下,蒸发成水汽升到高空,在风力推动下,部分水汽被吹向大陆,在适当条件下凝结成水滴下降,经地面汇集补给河川径流,汇入海洋。
