摘要本工程以发电为主，同时兼顾灌溉、供水、防洪及养殖等综合利用效益的跨流域开发的水利水电枢纽工程。在明确了建设目的并具有了建设依据和条件后设计的枢纽概况如下：B江水利枢纽为复合土工膜防渗堆石坝最大坝高54.7米，装机6400kW，电站设计水头174米，保证出力1461kW，装有两台3200kW机组，正常蓄水位276m，主坝长214.5米左右，上游边坡1：1.5,下游边坡250高程以上1：1.52， 250高程以下1：1.55。设计主要内容为： 根据防洪要求，对水库进行洪水调节计算，确定坝顶高程及溢洪道尺寸； 通过分析，对可能的方案进行比较，确定枢纽组成建筑物的型式、轮廓尺寸及水利枢纽布置方案； 详细做出大坝设计，通过比较，确定大坝的基本剖面和轮廓尺寸，拟定地基处理方案与坝身构造，进行水力、静力计算；进行专题一（趾板布置及计算）的设计； 施工组织设计，编写招标文件，进行专题二的设计，对招标文件技术条款编制进行深入研究。复合土工膜防渗堆石坝是一种新的坝型，其防渗材料复合土工膜的设计、施工、质量控制是该类坝型的技术关键，在本设计说明书第六章第三节有详细说明。本工程导流隧洞施工具有施工工作断面小，工期紧的特点，故其施工工艺是关键，在本设计说明书的有详细的说明。本次设计以一般混凝土面板堆石坝和一些已建复合土工膜堆石坝为参考，在注重各细部独立分项设计的同时，综合考虑了整体工程的统一性。在专题的编写中参考已建工程的趾板布置，对每块趾板的断面都进行详细的设计。在设计过程中既充分运用了所学知识，广泛参考了堆石坝设计、施工等相关书籍，并在规范规定内设计，体现了本设计的科学性、规范性。关键词：复合土工膜、堆石坝 、 防渗 、 边坡稳定 、导流隧洞 、施工组织设计、招标文件技术条款。Abstract This works is mainly in power generation, it also takes the irrigation, water supply, flood protection and comprehensive utilization of breeding into account .it is a multifunction hydropower project. Clear the purpose of building and construction ,with the design basi and conditions are as follows hub Overview: B Jiang Project impermeable geomembrane composite hub for the largest rock-fill dam height of 54.7 meters, installed capacity of 6400kW, power plant design head 174 meters to ensure that efforts 1461kW, with two 3200kW units, normal water level 276m, the main dam of about 214.5 meters long, upstream slope is 1:1.5, downstream slope is 1:1.52 above 250 elevation, 1:1.55 below elevation 250. The design of the main contents as follows: In accordance with the requirements of flood control, flood regulation on the calculation of the reservoir to determine the top of the dam height and spillway size; Through analysis of the program may be compared to determine the type of hub for the composition of buildings, the outline of foot . Layout-inch and water programs; Detailed design to make the dam, through comparison, to determine the basic profile of the dam and contour size, preparation of foundation and dam body to deal with the program structure for hydro, static calculation; thematic one (layout and calculation of the plinth) of the design; Construction design, preparation of tender documents, the second thematic design, tender documents for the preparation of the technical terms of an in-depth study. Impermeable geomembrane composite rockfill dam is a new type of dam, the impermeable geomembrane composite materials the design, construction, quality control is a kind of dam-based technology the key to the design specification in the Chapter VI 3 is described in detail. Construction of diversion tunnel of the project construction work with a small cross-section, characterized by tight time limit, so the construction technique is the key in the design specification is described in detail. The design of general concrete faced rockfill dam and a number of composite geomembrane has been rock-fill dam built as a reference, pay attention to detail in the breakdown of the design of an independent at the same time . Both during the design process, full use of the knowledge, extensive reference to the rock-fill dam design, construction and other related books, and design requirements in the specification, the design reflects the scientific and normative. Key words: composite geomembrane, rockfill dam, seepage, slope stability, diversion tunnel, construction of organizational design, the technical provisions of tender documents.3断面hAXRR(1/6)Cv12.2622.614.521.561.08107.6513.1622.22214.41.531.07107.3213.5232.1421.414.281.501.07106.9713.9042.0820.814.161.471.07106.6214.3052.0220.214.041.441.06106.2514.7361.9619.613.921.411.06105.8715.1871.91913.81.381.05105.4715.6681.8418.413.681.351.05105.0616.1791.7817.813.561.311.05104.6416.71101.7217.213.441.281.04104.2017.30111.6616.613.321.251.04103.7417.92121.61613.21.211.03103.2618.59131.5415.413.081.181.03102.7619.32141.4814.812.961.141.02102.2420.10151.4214.212.841.111.02101.6920.95161.3613.612.721.071.01101.1221.87171.31312.61.031.01100.5222.88181.2412.412.480.991.0099.8923.99191.1811.812.360.950.9999.2325.21201.0310.312.060.850.9797.4128.88av2/(2*9.81)EsEsv_R_C_J_i-J_9.2711.539.7911.990.4513.341.54107.490.010.2810.3412.480.5013.711.51107.150.010.2810.9513.030.5514.101.48106.800.010.2811.6113.630.6014.521.45106.430.010.2812.3314.290.6614.951.42106.060.010.2813.1215.020.7315.421.39105.670.020.2713.9915.830.8115.911.36105.270.020.2714.9516.730.9016.441.33104.850.020.2716.0117.731.0017.001.30104.420.020.2717.1918.851.1217.611.26103.970.020.2718.5020.101.2518.261.23103.500.030.2619.9721.511.4118.961.19103.010.030.2621.6223.101.5919.711.16102.500.030.2623.4924.911.8120.531.12101.960.040.2525.6126.972.0621.411.09101.410.040.2528.0329.332.3622.381.05100.820.050.2430.8032.042.7223.441.01100.210.050.2434.0235.203.1524.600.9799.560.060.2344.6545.6810.4827.050.9098.320.080.21Sis1.621.621.783.401.965.352.167.522.409.922.6612.582.9615.543.3118.853.7122.574.1826.754.7431.495.3936.876.1743.047.1150.158.2758.429.7068.1211.5279.6413.8793.5150.79144.30目录摘要- 4 -ABSTRACT- 5 -第一章 综合说明- 1 -1.1 工程特性表- 1 -1.2 建设目的和依据- 3 -1.3 建设的条件- 3 -1.4 建设的规模及综合利用效益- 3 -1.4.1 建设规模- 3 -1.4.2 综合利用效益- 3 -第二章 自然地理条件- 5 -2.1 地形条件- 5 -2.2 水文特性- 5 -2.3 工程地质条件- 5 -2.3.1库区工程地质- 5 -2.3.2坝址工程地质- 6 -2.3.3 引水发电隧洞工程地质条件- 9 -2.4 气象、地震及其他- 9 -2.4.1 气象、地震- 9 -2.4.2 天然建筑材料- 9 -第三章 设计条件和设计依据- 11 -3.1 设计任务- 11 -3.2 设计依据- 11 -第四章 洪水调节计算- 13 -4.1 洪水调洪演算- 13 -4.1.1 洪水调洪演算原理- 13 -4.1.2洪水调洪演算方法- 14 -4.2 洪水标准分析- 14 -4.3 洪水建筑物的型式选择- 15 -4.4 调洪演算及泄水建筑物尺寸（孔口尺寸/堰顶高程）的确定- 16 -4.4.1 调洪演算过程- 16 -4.4.2 洪水过程线的模拟- 16 -4.4.3 计算公式- 17 -4.4.4 计算结果- 17 -4.4.5 方案选择- 18 -4.4.6 坝顶高程的确定- 18 -4.4.7 闸门设计- 20 -4.4.8 泄水建筑物的设计- 20 -第五章 主要建筑物型式选择及枢纽布置- 21 -5.1 坝轴线确定- 21 -5.2 枢纽等别及组成建筑物级别- 22 -5.3 坝型选择- 23 -5.3.1 定性分析- 23 -5.3.2 定量分析- 27 -5.4 泄水建筑物型式选择- 28 -5.5 水电站建筑物- 29 -5.6 枢纽方案的综合比较- 30 -5.6.1 挡水建筑物复合土工膜防渗堆石坝- 30 -5.6.2 泄水建筑物正槽溢洪道- 30 -5.6.3 水电站建筑物- 30 -第六章 第一主要建筑物设计- 31 -6.1 大坝轮廓尺寸及防浪墙设计- 31 -6.1.1 L型挡墙顶高程及坝顶高程、宽度- 31 -6.1.2 坝体分区- 31 -6.1.3 L型挡墙设计- 32 -6.1.4 坝坡与马道- 41 -6.2 堆石料设计- 42 -6.2.1 堆石料基本特性参数- 42 -6.2.2 主、次堆石料设计- 42 -6.2.3 垫层、过渡层设计- 42 -6.2.4 堆石体设计技术参数表- 42 -6.2.5 堆石体填筑技术参数表- 43 -6.3 复合土工膜设计- 43 -6.3.1 复合土工膜的选型和分区- 43 -6.3.2 土工膜强度及厚度校核- 45 -6.4 大坝稳定分析- 46 -6.4.1 计算原理及方法- 46 -6.4.2 坝坡稳定分析- 48 -6.4.3 坝坡面复合土工膜的稳定分析- 48 -6.5 副坝设计- 49 -6.5.1 副坝及主坝的连接及副坝型式选择- 49 -6.5.
