【摘要】：水庫可分為山區(qū)水庫和平原水庫,而平原水庫又可分為河道型平原水庫和圍壩型平原水庫兩種類型。淄博市是個(gè)缺水的城市,修建水庫是解決這一矛盾的方法之一,但淄博市又位于魯中山區(qū)向黃泛平原的過渡地帶,地形地貌特殊,對(duì)于淄博南部山區(qū)沂源縣、淄川區(qū)以及博山區(qū)三個(gè)區(qū)縣,能夠充分利用山區(qū)的有利地形,通過修建以土石壩、混凝土壩或砌石壩等常規(guī)壩型為主的山區(qū)水庫來解決水資源矛盾問題,對(duì)于北部平原高青縣和桓臺(tái)可以通過修建全圍壩式平原水庫來解決水資源矛盾問題,但對(duì)位于淄博中部丘陵過渡區(qū)域的張店區(qū)、臨淄區(qū)和周村區(qū)三個(gè)區(qū)縣,如果要通過修建水庫來解決供水矛盾的問題,尚沒有比較完善的水庫壩型可供選擇。平原水庫相比較山區(qū)水庫具有其獨(dú)有的特征,比如水庫軸線多為圓形、橢圓或折線形；壩線長、水面吹程大,風(fēng)浪爬高而產(chǎn)生的越浪問題難以解決；壩體高度一般為2-8m,超過10m壩高的平原水庫工程比較少見；壩體迎水坡護(hù)坡工程投資較大,約占工程總投資的40%-50%,而山區(qū)水庫壩體迎水面護(hù)坡投資一般不到總投資的10%；平原水庫區(qū)適宜筑壩的表層粘壤土土層薄,基礎(chǔ)多為較深的粉細(xì)砂土,存在的滲漏和造成周圍地區(qū)次生鹽漬化問題較為嚴(yán)重；平原水庫一般情況下沒有發(fā)電任務(wù)等。而在山丘區(qū)修建平原水庫,由于受到局部地形的影響,一般采用半開挖半回填的方式進(jìn)行,就造成了平原水庫的局部壩高基本會(huì)在10m以上,比如本論文研究背景下新建的平原水庫最大壩高達(dá)到了17m,必然會(huì)對(duì)平原水庫的滲漏穩(wěn)定安全造成較大的影響；還有就是筑壩土料的選擇,如何更好的利用開挖出的土石方作為筑壩材料將對(duì)整個(gè)工程的投資產(chǎn)生不小的影響等。本論文結(jié)合引太入張工程急需修建一調(diào)蓄工程為背景,通過搜集大量國內(nèi)外平原水庫設(shè)計(jì)研究資料,結(jié)合工程的實(shí)際情況提出了新建半圍壩式平原水庫方案,從引太入張供水渠道特點(diǎn),圍繞滿足調(diào)蓄工程需要,提出可行的工程方案,經(jīng)過詳細(xì)的調(diào)查分析論證,闡述了半圍壩式平原水庫在該工程的優(yōu)點(diǎn)；再結(jié)合所選定方案所在項(xiàng)目的地形地貌特點(diǎn)及工程地質(zhì)資料,對(duì)圍壩及庫區(qū)進(jìn)行詳細(xì)的設(shè)計(jì)及優(yōu)化,并通過建立數(shù)學(xué)模型對(duì)圍壩進(jìn)行了滲流穩(wěn)定分析,闡述了半圍壩式平原水庫在該工程上應(yīng)用的可行性,為山區(qū)向平原過渡地帶或丘陵地帶修建平原水庫提供了內(nèi)容詳實(shí)的參考資料。
[Abstract]:Reservoirs can be divided into mountain reservoirs and plain reservoirs, and plain reservoirs can be divided into river plain reservoirs and surrounding dam plain reservoirs. Zibo is a city short of water, and the construction of reservoirs is one of the ways to solve this contradiction. However, Zibo City is located in the transitional zone from the mid-Shandong mountainous area to the Yellow River Pan-Plain, with special landforms and landforms. For the three counties of Yiyuan County, Zichuan District and Boshan District in the southern mountain area of Zibo, it can make full use of the favorable terrain in the mountainous area, and through the construction of earth-rock dams, Conventional dam types, such as concrete dams or stone masonry dams, are used to solve the problem of water resources contradiction. In the northern plain, Gaoqing County and Huantai can solve the problem of water resources contradiction through the construction of fully enclosed dam type plain reservoirs. But for Zhangdian District, located in the transition region of the central hills of Zibo, Linzi District and Zhoucun District, if we want to build reservoirs to solve the problem of water supply contradictions, There is no perfect reservoir dam type to choose from. Compared with mountain reservoir, plain reservoir has its unique characteristics, for example, the reservoir axis is mostly circular, elliptical or curved, the dam line is long, and the water surface blowing distance is large. It is difficult to solve the problem of surpassing waves caused by wind wave climbing; the dam body height is generally 2-8 m, and the plain reservoir project with dam height exceeding 10 m is rare, and the investment in slope protection project of dam body facing water slope is large. About 40-50% of the total investment in the project, while the investment in slope protection of the dam body in the mountainous area is generally less than 10% of the total investment; the surface clay loam soil layer suitable for dam construction in the plain reservoir area is thin, and the foundation is mostly silty sand soil. The problems of leakage and secondary salinization in the surrounding area are serious, the plain reservoir has no power generation task in general, and the construction of plain reservoir in hilly area is affected by local topography. Generally, half excavation and half backfill is adopted, which results in the local dam height of the plain reservoir being more than 10 m. For example, under the background of this paper, the maximum dam height of the newly built plain reservoir has reached 17m, which will inevitably have a great impact on the stability and safety of the leakage of the plain reservoir. How to make better use of excavated earth and rock as dam material will have a great impact on the investment of the whole project. By collecting a large number of domestic and foreign data on the design of plain reservoirs, combined with the actual situation of the project, the scheme of newly built semi-enclosed dam type plain reservoirs is put forward. The characteristics of water supply channels are brought into the water supply channels from Taitai to meet the needs of the regulation and storage projects. A feasible project scheme is put forward. After detailed investigation, analysis and argumentation, the advantages of semi-enclosed dam plain reservoir in this project are expounded, and the topographic and geomorphological characteristics and engineering geological data of the selected project are combined. Detailed design and optimization of the surrounding dam and reservoir area are carried out, and the seepage stability of the surrounding dam is analyzed by establishing a mathematical model. The feasibility of the application of the semi-enclosed dam type plain reservoir in this project is expounded. It provides detailed reference materials for constructing plain reservoir in the transition zone from mountainous area to plain or hilly area.
