【正文】 Flood Regulating and Calculating to get the best width of the overflow weir Orifice and the altitude of weir top, then pare different types of earthrock features in the course of construction, technical and economic advantages and disadvantages, and ultimately determine the type of clay dam earthrock core, and the outline of an initial size of the dam. Through the soil and then design, the control indicators to determine the gravel and clay material yard field position. Once again chosen the three typical crosssection of dam for seepage calculation, draw work maps, checking the seepage infiltration gradient to determine whether to meet the requirements. Use Visual basic programming to analyze the stability, and ultimately to carry out detailed structural design of the dam. The second step, to enter the main building design stage. To determine the type and the dam site and dam axis. In addition to determine the position of the hub structures, including retaining structures, drainage structures, such as hydropower plants. The third step is the second major phase of building design. To determine the size of Discharge structure, type and structure of the tunnel for discharge. To select the axis and then proceed hydraulic calculation, from the discharge capacity of more than pieces of headroom, and washed out from the depth of checking the feasibility of the design. Finally design the detail of the Structural . The fourth step is a preliminary design of the construction anization. Diversion to determine standards, the construction phases. Set start date, closure date, flood detention date, the date of reservoir impoundment, the initial generation date and pletion date. Finally enter the topic design, calculate the tunnel lining stress, the use of geotechnical analysis software is the rationale for calculating the lining and reinforcement. The design based on the Code for Design of roller pacted earth dam SL2742021, along with reference to the relevant information with the earth dam and books. Due to the limited knowledge about the design of the inappropriate and wrong, ask for his approval in criticism. During the design process, very appreciate for the directions by Professor Shu YiMing, Wang LingLing, Su HuaiZhi, once again express our sincere gratitude. The design period is a total of nine weeks. 水利水電工程專業(yè)畢業(yè)設計 3 目 錄 第一章 前 言 ........................................................................................................... 6 畢業(yè)設計主要目的和作用 ....................................................................................... 6 設計對象和背景 ..................................................................................................... 6 設計過程與方法 ..................................................................................................... 6 了解任務書和熟悉、分析原始資料 .................................................................... 6 洪水調節(jié)計算 .................................................................................................. 6 主要建筑物形式選擇和水利樞紐布置 ............................................................... 6 第一主要建筑物 —— 攔河壩設計 ...................................................................... 7 第二主要建筑物 —— 壩外泄水道設計 ................................................................ 7 決定樞紐的施工導流方案，安排施工的控制性進度 .......................................... 7 預期效果 ................................................................................................................ 7 第二章 土石壩工程概況 ................................................................................................. 8 工程流域概況 ......................................................................................................... 8 當?shù)貧夂蛱卣? ......................................................................................................... 8 氣溫情況 ......................................................................................................... 8 濕度情況 ............................................................................................................ 9 降水量情況 ........................................................................................................ 9 風力和風向 .......................................................................................................... 9 當?shù)厮奶卣? ........................................................................................................... 10 年日常徑流資料 ................................................................................................. 10 洪峰流量資料 .................................................................................................... 10 固體徑流資料 .................................................................................................... 10 工程地質資料 ........................................................................................................... 10 水庫地質資料 .................................................................................................... 11 壩址地質資料 .................................................................................................... 11 地質構造資料 .................................................................................................... 13 水文地質條件 .................................................................................................... 13 地震資料 ........................................................................................................... 14 建筑材料 .................................................................................................................. 14 料場的位置與儲量資料 ...................................................................................... 14 物理力學性質概述 ............................................................................................. 14 經(jīng)濟資料 ..........
