1、毕业设计 题 目：青海省玉树州查隆通水电站厂房设计 （方案二）姓 名： 陈笑彭学 号： 0903105032 指 导 教 师： 解宏伟 万英正专 业 年 级： 09级水利水电工程所在学院和系： 水利电力学院完 成 日 期： 2013/6/6答 辩 日 期： 2013/6/14 青海省玉树州查隆通水电站厂房设计（方案二）摘要本毕业设计承担查隆通水电站工程中水电站厂房设计的工作。根据已有的原始资料和该处地形图进行设计，主要内容有：综合各种因素进行水电站站址的选择，水电站厂房选型及布置，通过水力计算确定水轮机组的主要参数，对比可选机组性价比及相关影响因素选择最优水轮机组，水力计算还确定了冲砂孔、压力
2、管道、尾水渠等尺寸，进一步计算并确定厂房各层水平方向的尺寸及厂房各重要层面的高程，然后根据厂房尺寸对其中交通桥、吊车梁、厂房地板、厂房主梁、柱、闸墩等主要构件进行强度配筋计算，并对其进行抗裂、挠度等方面的验算，由于厂房地基安全性要求较高，在对其进行抗剪稳定性计算之后采用Ansys软件对地基设计进行分析，进一步验算其稳定性。最后根据要求绘制相应的平面布置图和剖面图以及厂房主要构件的配筋图。玉树州是青海省唯一没有被主电网覆盖的地区，电力供应主要依靠地方小水电，电源供应能力差，保证率低。电网电压等级分别为35kV、10kV、0.4kV，各水电站大多独立运行自成一片，网架尚未形成，供电线路主要为10k
3、V单回路，除玉树县与称多县、治多县与曲麻莱县分别联网外，囊谦县和杂多县为独立电网，由于电源容量小，电网主要覆盖在县城及周边村社，大部分乡镇村社尚未通电。查隆通电站装机容量10500kW，多年平均发电量4329.64104kWh，是子曲河上规划的第三座梯级电站。查隆通电站上马后可基本解决玉树州目前的电力电量不足问题，为玉树电网提供支撑电源，同时给其他河流电站提供施工电源。该电站建成后可实现110kV电网与结古、囊谦、杂多联网运行，保证全州的电力供应，提高供电的保证率和可靠性，从而将大力推动玉树州经济和各项事业的发展。查隆通水电站具有较好的开发建设条件、良好的经济效益和社会效益。为了尽快改善该地区
4、的贫困落后面貌，推动地区经济快速发展，充分开发和利用丰富的水电资源，建设查隆通水电站工程是十分必要的。本电站的设计水头为17米，单机容量3500kW，共三台机组，总装机容量10500kW。 关键词：选型、布置、尺寸及高程、装机容量、强度、抗裂、稳定性。YUSHUZHOU CHARLON WATER POWER STATION IN QINGHAI PROVINCE PLANT DESIGN (PLAN II)AbstractGraduation bear out long passes of hydropower hydropower engineering design work.

5、rding to has some original information and the Department topographic maps for design, main content has: integrated various factors for hydropower station station site of select, water power station plant selection and the layout, through hydraulic calculation determines hydro-unit of main parameter
6、, contrast can selected unit cost and the related effect factors select optimal hydro-unit, hydraulic calculation also determines has rushed sand hole, and pressure pipeline, and tail Canal, size, further calculation and determines plant the layer level direction of size and the plant the important
7、level of elevation, then according to plant size on which traffic bridge , Crane beams, factory floor, building girders, columns, piers and other major component strength reinforcement calculation and checking computation of crack resistance, deflection, and other aspects of it, because of the highe
8、r plant Foundation security requirements, to shear stability calculation using the Ansys software to analyze the Foundation design, further checking it is stable. Upon request, the final draw a floor plan and corresponding reinforcement diagram of the main components of profiles as well as building.
9、 Yushu is only covered in main grid area, Qinghai province, relies mainly on local small hydropower electricity supply, poor power supply, guaranteed low rates. Grid voltages of 35kV, respectively, 10kV, hydropower stations mostly operate independently from, and grid has not been formed, mostly 10kV
10、 one-circuit of power supply line, apart from yushu County and Chenduo County, outside the Zhiduo County networking with Qumalai County respectively, Nangqian County and Zaduo County as an independent power, due to the small capacity, power major coverage in the town and the surrounding villages, th
11、e majority of township village is not powered up. Charlon flux power station installed capacity 10500kW, 4329.64x104kW annual average generating capacity h, is planning on a child: taking daqu third cascade hydropower station. Charlon-pass power plant on a horse can resolve the current electricity s
12、hortage in yushu State, support for yushu power grid power, and construction of power plants provide power to other rivers. 110kV power network can be realized after the completion of the power station with the jiegu, nangqian and Heteropoly networking operation, guarantees the State of power supply
13、, guarantee rate and reliability of power supply, so as to vigorously promote yushu prefectures economic and development of various undertakings. Charlon-way with better conditions for development and construction of hydropower stations, good economic and social benefits. Poverty as soon as possible
14、 in order to improve the regions backward look, promote regional economic development, full development and utilization of rich hydropower resources, Charlon-building water power station project is essential. Head 17 m power station design, single capacity 3500kW, all three units, the total installe
15、d capacity of 10500kW. Key words: selection, layout, size and height, capacity, strength and crack resistance and stability.绪论目 录41水利电力学院 前言21 绪论31.1项目建设背景及任务31.2设计基本资料31.3原始资料42 厂房布置52.1考虑因素52.2厂房形式52.3 交通条件52.4 开挖方量52.5施工场地的选择52.6 泄洪产生的影响52.7生活区和管理区位置的协调52.8对其他工程的协调影响63 水轮机组选择及其水头损失计算63.1 水头计算63.2水轮机主要参数的确定63.3 泄洪冲砂孔水力计算
