水利枢纽堆石坝设计说明书.rar

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:,装机6400kW,电站设计水头174米,保证出力1461kW,装有两台3200kW机组,,,上游边坡1:,下游边坡250m高程以上1:,250m高程以下1:。
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。
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和第七章第五节有详细说明。
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、导流隧洞、施工组织设计
Abstract
The purpose of this design is to develop the water resources of B Jiang Basin, constructing a power-based, taking into account irrigation, water supply, flood protection and aquaculture Etc. prehensive utilization efficiency, such as the development of inter-basin water conservancy and hydropower project.
After clearing the purpose of the construction, having the basis and conditions of the construction the project is designed as follows:B Jiang Project is posite geomembrane impermeable rock-fill dam height of ,installed 6400kW,the design head of power station is 174m, the firm capacity is 1461kW, with two engine unit of 3200Kw, the normal water level is , the length of the main dan is about ,upstream slope is 1:, and downstream slope is 1: above 250 elevation, 1: below elevation 250.
The primary coverage of the design is: ascertain the crest elevation; Pa-selection; the first major building design; anization design.
posite geomembrane rockfill dam is a new type of dam, the impermeable posite he design, construction, quality control are the key technology of such dam ,which are explained in more details in the design of Chapter VI of the third statement and Chapter VII of the fifth statement.
The diversion tunnel construction project have the characteristics of small construction work on the section, tight time limit, so its construction techno
