【摘要】：我國是一個(gè)水資源相對匱乏的國家，日益嚴(yán)重的水資源短缺和水環(huán)境污染，加重了對水資源問題研究的重要性。對于水資源更加稀缺的北方來說，修建水庫無疑是一種抗洪和防災(zāi)、并集水資源開發(fā)利用為一體的重要手段，也更加有利于構(gòu)建穩(wěn)定的國民基礎(chǔ)經(jīng)濟(jì)。近年來，隨著社會(huì)經(jīng)濟(jì)的不斷發(fā)展，越來越多的水庫在全國各地不斷建立起來，同時(shí)一些不科學(xué)的水庫建設(shè)項(xiàng)目潛在的負(fù)面影響也逐漸地顯露出來。在缺水地區(qū)，水庫對于人們的生活生產(chǎn)活動(dòng)是十分重要的，因此通過構(gòu)建合理的水庫體系，，能更好的協(xié)調(diào)處理好水庫建設(shè)與社會(huì)經(jīng)濟(jì)發(fā)展的關(guān)系，具有重要的社會(huì)經(jīng)濟(jì)和環(huán)境意義。 本文針對吉林省德惠市丹城子水庫建設(shè)的相關(guān)問題開展研究，總結(jié)了丹城子水庫建設(shè)研究的必要性和可行性。 文章分別從水庫的洪水設(shè)計(jì)、主要構(gòu)筑物構(gòu)建、環(huán)境分析和工程管理等幾個(gè)方面，對丹城子水庫進(jìn)行設(shè)計(jì)研究。首先主要介紹水庫的洪水設(shè)計(jì)，對吉林模型法、羅氏法和水科所法的設(shè)計(jì)結(jié)果進(jìn)行對比分析，最終選用羅氏法的計(jì)算結(jié)果。其次對主要構(gòu)筑物進(jìn)行介紹，這要涉及工程土壩、泄洪灌溉洞及進(jìn)水涵管的設(shè)計(jì)。再次分析了丹城子水庫的環(huán)境現(xiàn)狀，進(jìn)行環(huán)境保護(hù)設(shè)計(jì)。最后從從施工導(dǎo)流、料場選擇與開采、主體工程施工及施工輔助設(shè)施的配備等方面對工程管理進(jìn)行介紹。 經(jīng)過以上的設(shè)計(jì)研究，最終確定丹城子水庫設(shè)計(jì)洪水標(biāo)準(zhǔn)為10年設(shè)計(jì)，50年校核。校核洪水位為163.74m，最大庫容為76.0萬m3，設(shè)計(jì)水位161.51m，設(shè)計(jì)庫容25.4萬m3，正常高水位161.3m，興利庫容21.3萬m3，死水位158.5m，死庫容1.09萬m3。 根據(jù)調(diào)洪演算結(jié)果，確定丹城子水庫工程規(guī)模屬�。ǘ┬�，工程等別為Ⅴ等，主要建筑物為5級(jí)，次要建筑物為5級(jí)。工程總體布置樞紐工程基本上由土壩、泄洪灌溉洞及進(jìn)水涵管三部分構(gòu)成。丹城子水庫新建工程初步設(shè)計(jì)概算總投資為649萬元。
[Abstract]:China is a country with relatively scarce water resources. The increasingly serious shortage of water resources and the pollution of water environment have aggravated the importance of the research on water resources. For the north, where water resources are more scarce, the construction of reservoirs is undoubtedly an important means to prevent flood and prevent floods, and to combine the development and utilization of water resources as an important means, and is also more conducive to the construction of a stable national basic economy. In recent years, with the development of social economy, more and more reservoirs have been established all over the country, and the potential negative effects of some unscientific reservoir construction projects have been gradually revealed. In water-scarce areas, reservoirs are very important for people's daily production activities. Therefore, by constructing a reasonable reservoir system, we can better coordinate the relationship between reservoir construction and social and economic development. Has the important social economy and the environment significance. Based on the research on the construction of Danchengzi Reservoir in Dehui City, Jilin Province, this paper summarizes the necessity and feasibility of the study on Danchengzi Reservoir Construction. This paper studies the design of Danchengzi Reservoir from the aspects of flood design, construction of main structures, environmental analysis and engineering management. Firstly, the flood design of reservoir is introduced, and the design results of Jilin model method, Roche method and hydrology method are compared and analyzed. Finally, the calculation results of Roche method are selected. Secondly, the main structure is introduced, which involves the design of engineering earth dam, flood discharge irrigation tunnel and inlet culvert. The environmental status of Danchengzi Reservoir is analyzed again, and the design of environmental protection is carried out. Finally, the project management is introduced from the aspects of construction diversion, selection and mining of material yard, construction of main engineering and equipment of construction auxiliary facilities. The design flood standard of Danchengzi Reservoir is determined to be 10 years design and 50 years check. The check flood water level is 163.74 m, the maximum storage capacity is 760000 m3, the design water level is 161.51 m, the design capacity is 254000 m3, the normal high water level is 161.3 m, the profit storage capacity is 213000 m3, the dead water level is 158.5 m, and the dead storage capacity is 10900 m3. According to the result of flood control calculation, it is determined that the project scale of Danchengzi Reservoir is small (type 2), the engineering grade is 鈪
