【摘要】：我國水庫為數(shù)眾多,累計興建了約8.7萬多座,這些水庫不僅增強了江河綜合防洪能力,而且提高了水資源的調(diào)控水平,在防洪、灌溉、供水、發(fā)電等方面發(fā)揮了巨大效益,在保障國民經(jīng)濟建設(shè)以及農(nóng)田水利建設(shè)中發(fā)揮了重要的作用。但由于水庫的長期運行,工程存在老化、破壞、自然侵蝕等現(xiàn)象,許多水庫出現(xiàn)了防洪標(biāo)準(zhǔn)偏低,達(dá)不到規(guī)范的問題,從而形成了大量的病險水庫,不僅造成水庫不能正常運行,而且嚴(yán)重威脅著下游人民生命財產(chǎn)的安全。因此,對水庫存在的問題及隱患進(jìn)行排查、修補、對病險水庫進(jìn)行加固,實屬當(dāng)務(wù)之急。本文結(jié)合具體工程,在實地調(diào)查研究、收集資料的基礎(chǔ)上采用理論計算與實際分析相結(jié)合的方法,對浙江省臨海市坑里水庫除險加固工程進(jìn)行了設(shè)計研究。主要研究內(nèi)容為：針對攔河壩存在的壩體滲流不安全、不穩(wěn)定,存在滲流隱患；攔河壩上、下游壩坡不穩(wěn)定,攔河壩粘土心墻截水槽下游測與下游含礫砂粉質(zhì)粘土副心墻底部無反濾,上、下游護(hù)坡不安全,壩頂結(jié)構(gòu)不安全,坑里水庫攔河壩存在嚴(yán)重的結(jié)構(gòu)安全隱患等問題,經(jīng)綜合考慮,擬選具有防滲可靠、耐久性及安全度較高、可靠性較強、施工方便、防滲處理較徹底以及投資較合理等優(yōu)點的懸掛式低彈�；炷练罎B墻防滲為除險加固方案。同時,經(jīng)過大壩滲流、大壩抗滑穩(wěn)定、大壩應(yīng)力、大壩左岸壩頭擋墻穩(wěn)定和基礎(chǔ)應(yīng)力、上游護(hù)坡厚度等的計算,確定攔河壩除險加固設(shè)計。針對溢洪道存在的問題,從溢洪道除險加固、溢洪道除險加固基礎(chǔ)處理和溢洪道除險加固設(shè)計計算三個方面,進(jìn)行溢洪道除險加固設(shè)計,確�？永锼畮斓陌踩�,并發(fā)揮其原有設(shè)計功能。
[Abstract]:There are a large number of reservoirs in China, with a cumulative construction of more than 87000. These reservoirs not only enhance the comprehensive flood control capacity of rivers and rivers, but also improve the level of water resources regulation and control. They have played a great role in flood control, irrigation, water supply, power generation, and so on. In the protection of national economic construction and irrigation and water conservancy construction has played an important role. However, due to the long-term operation of the reservoir, the existence of aging, destruction, natural erosion and other phenomena, many reservoirs have low flood control standards, which can not reach the standard, thus forming a large number of dangerous reservoirs. It not only causes the reservoir not to operate normally, but also threatens the safety of people's life and property. Therefore, it is urgent to investigate, repair and reinforce the reservoir. In this paper, based on field investigation and data collection, combined with concrete project, the method of combining theoretical calculation with practical analysis is adopted to design and study the project of eliminating danger and strengthening the reservoir in Linhai City, Zhejiang Province. The main research contents are as follows: in view of the dam body seepage is unsafe, unstable, percolation hidden danger, upstream and downstream dam slope is unstable, The bottom of the silty clay core wall with gravel is not filtered, the slope is not safe, the structure of the dam top is not safe, and the dam of the Keng Li reservoir has serious structural safety hidden trouble, and so on, the downstream measurement of the clay core wall intercepts the flume and the bottom of the gravel silty clay accessory core wall, the slope protection of the upper and lower reaches of the dam is unsafe. After comprehensive consideration, it is suggested that the anti-seepage scheme of hanging low-elastic modulus concrete impervious wall with the advantages of high durability, high safety, high reliability, convenient construction, thorough anti-seepage treatment and reasonable investment is selected as the anti-seepage and strengthening scheme. At the same time, through the calculation of dam seepage, dam anti-slide stability, dam stress, dam head retaining wall stability and foundation stress on the left bank of the dam, and the thickness of upstream slope protection, the design of dam reinforcement is determined. In view of the existing problems of spillway, from three aspects of spillway danger removal reinforcement, spillway danger removal reinforcement foundation treatment and spillway design and calculation, the spillway danger removal reinforcement design is carried out to ensure the safety of the reservoir in the pit. And give play to its original design function.
