郭庄水利枢纽.doc

摘要 郭庄水利枢纽工程建筑物包括：主坝、溢洪道、导流建筑物、灌溉发电隧洞。按SDJ12—78规范中设计标准，工程等级为3等，水利枢纽为中型，主要建筑物按三级设计，次要建筑物按四级设计，临时建筑我按五级设计。 根据实际与现有条件，本设计主要针对其中的主坝和溢洪道进行详尽的设计。 主坝设计包括：坝工设计，渗透分析与计算，坝坡稳定与计算，地基处理，细部构造，两岸连接建筑物等。 溢洪道设计包括：引水渠，泄水槽，控制段及出口效能段的结构布置，水力计算（包括泄水过程、水面线及消能计算），细部构造等。 关键字：水利枢纽工程，挡水建筑物，溢洪道  Abstract Water conservancy vital point engineering building in the Guo zhuang mainly includes: Main dam ,spillway, lead to follow to relapse excessive water hole, irrigation to generate electricity station factory premises to constitute .Press the SDJ12—78 the design in the norm standard ,the engineering grade is a NO.3 quality ,reservoir vital point is medium—sized ,the main building is according to the X-rated design ,the next in importance building press four classes design ,and the building presses five classes design at the time. Graduate the design is student’s last teaching link during the period of school ,according to the actual and existing condition ,this main dam and spillway which designs to mainly as to it’s win carry on a detailed design. The main dam design include: the dam work design, permeates analysis and computes ,dam ascent stability and calculation ,foundation processing ,minute part structure ,cross－straits conduction building eta. The spillway design include :lead a water dike and leak water the structure decoration that slot ,control segment and exit eliminate an ability segment ,water conservancy calculation (include to leak water process, surface line and eliminate can compute),minute part structure etc. Key words: water conservancy，vital point engineering ,blocks water building  目录 摘要 1 Abstract 2 第1章 总述 5 1.1 概况 5 1.2 基本资料 5 1.2.1 水文资料 5 1.2.2 地形、地质 8 1.2.3 当地建筑材料 8 1.2.4 水利规划计算成果 10 1.3 工程综合说明 10 第2章 枢纽布置 11 2.1 枢纽组成及建筑物级别 11 2.2 建筑物类型及枢纽布置方案比较及选定 12 2.2.1 建筑物类型 12 第3章 土坝设计 15 3.1 坝型选择 15 3.2 地基处理及断面拟定 15 3.2.1地基处理 16 3.2.2断面拟定 16 3.3 渗流计算 21 3.3.1 计算说明 21 3.3.2 渗流计算 23 3.4 稳定分析 29 3.4.1计算说明 29 3.4.2稳定计算 30 3.4.3综合分析 36 3.5 细部构造设计 36 3.5.1坝顶布置 36 3.5.2坝的防渗体和排水设备 37 3
