钟吕水利枢纽复合土工膜防渗面板堆石坝设计说明书（新）.doc

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53.2m，装机6400kW，电站设计水头174m，保证出力1461kW，装有两台3200kW机组，正常蓄水位276.5m，主坝长190m左右，上游边坡1：1.5，下游251高程马道上部边坡1：1.52，马道下部边坡1：1.54。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。并进行了主体工程投标文件技

2、术标的编写，其中重点对本次设计专题-技术标的施工组织设计进行了设计及编写。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，对钟吕水库主体工程的施工组织进行了设计，确保按期完成本标段工程。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、施工技术等相关书籍，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、
