1、摘 要本次设计主要是开发利用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江水利枢纽混凝土面板堆石坝高52.9m米,装机6400KW,电站设计水头174米,多年平均发电量为1700万KWh,保证出力1461KW。本电站装有两台3200KW机组,主坝长206米左右,上游边坡1:1.55,下游边坡1:1.55。本混凝土面板堆石坝的设计主要包括坝高、趾板、面板、溢洪道的设计以及一些细节部分的设计。混凝土面板堆石坝其防渗结构为混凝土面板、趾板、防浪墙、水平缝、垂直缝、帷幕的
2、设计、施工、质量控制是该类坝型的技术关键,本次设计以一般为参考,重点考虑趾板及泄水建筑物的设计,同时,堆石坝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,有广泛参考了设计施工方面的有关书籍。当然,这都是在规范规定内作的设计,体现了本工程的科学性和规范性。关键字:混凝土面板堆石坝、趾板、面板、溢洪道、副坝AbstractThe purpose of this design is to develop the water resources of B Jiang Basin,constructing a power-based, taking int
3、o account irrigation, water supply, flood protection and aquaculture Etc. of comprehensive 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
4、project is designed as follows:B Jiang Project is a composite geomembrane impermeable rock-fill dam height of 52.9 m,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 276.8m,the length of the main dan is ab
5、out 227.5m,the upstream slope is 1:1.55and downstream slope is 1:1.55.The design of concrete-face rockfill dam mainly concludes height of dam 、anchoring of footwall、the design of the slab 、the design of spillway and some other details .Compound geotechnological concrete face rockfill dam ,whose prev
6、ention of concrete face,concret face slab and wave wall,periphery joint ,vertical joint,curtain grouting -Compound geotechnological design, construction, quality control of membrane the technological key of dam type.The designs process above-mentioned is referenced to the former design of rock-fill
7、dam ,in pay attention to every detail while of designing , have and consult design and construction relevant books of respect extensively. Certainly, this design that is made in the regulation of standardizing , it is scientific, regulatory to reflect.Key words: conrete-face rockfill dam; Plinth; Pa
