1、摘 要钟吕水利枢纽是以发电为主,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:挡水建筑物为钢筋混凝土面板堆石坝,最大坝高55.5米,主坝轴线长220米,上下游边坡均为1:1.55,正常蓄水位276.6m,设计洪水位277.7m,校核洪水位279.2m。电站装机6400kW,设计水头174米,保证出力1461kW。设计主要内容为:1、根据防洪要求,对水库进行洪水调节计算,最终确定坝顶高程为280.0m; 2、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;3、详细做出大
2、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;4、确定趾板等的构造并进行初步设计阶段的施工组织设计;5、进行专题的设计:技术标的施工组织设计及进度计划。本次设计以已建的混凝土面板堆石坝为参考,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实际工程招投标阶段的施工组织设计文件,对本工程各分部工程进行详细的设计,编写了适合本工程施工阶段的施工组织设计文件和施工总进度计划。在设计过程中充分运用所学知识,广泛参考堆石坝设计、施工方面的相关书籍,严格遵照规范的规定进行设计,体现了本设计的科学性、规范性。关键词:钢筋混凝土面
