1、摘 要本次设计主要是为了开发利用 B 江流域的水利资源，建设一个以发电为主， 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 53.0 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 275.5m，主坝长 236.5 米左右，上游边坡 1：1.5,下游边坡 1：1.4。 本次设计主要内容为：经洪水调节确定坝顶高程；坝型的比选；第一主要建 筑物的设计；施工组织设计。并进行了导流隧洞投标文件的
2、编写，其中重点对本 次设计专题施工组织设计了设计及编写。 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 中参考已建工程的导流隧洞，对导流隧洞的施工组织进行了设计，确保按期完成 导流隧洞标段工程。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
