試析水電站的抗震措施設(shè)計(jì)
摘要：隨著經(jīng)濟(jì)的迅速發(fā)展以及科學(xué)技術(shù)水平的不斷提高，我國(guó)的水利建設(shè)取得了較大程度上的進(jìn)步，為我國(guó)民生事業(yè)的發(fā)展做出了突出貢獻(xiàn)。在進(jìn)行水利建設(shè)的過(guò)程中，需要對(duì)水電站進(jìn)行修建。對(duì)于水電站來(lái)說(shuō)，不僅要在修建時(shí)對(duì)其質(zhì)量高進(jìn)行一定程度的保證，還要十分注意后期的維護(hù)。本文主要針對(duì)水電站的抗震措施設(shè)計(jì)進(jìn)行研究與分析。在進(jìn)行研究時(shí)，選取某地一個(gè)水電站作為研究對(duì)象，這一水電站的地震設(shè)防烈度達(dá)到了9度。首先，我們對(duì)這一水電站的混凝土大壩進(jìn)行了較為全面的動(dòng)力分析，在分析過(guò)程中，主要采用了兩種分析方法，分別是數(shù)值計(jì)算法以及模型試驗(yàn)法。通過(guò)分析，我們對(duì)這一水電站大壩抗震的薄弱部位進(jìn)行了確定并對(duì)其有了一定程度的了解，然后根據(jù)實(shí)際情況提出了相應(yīng)的設(shè)計(jì)措施。
關(guān)鍵詞：水電站；混凝土大壩；抗震研究；設(shè)防烈度
Abstract: with the rapid development of economy and the improvement of science and technology, water conservancy construction of our country has made great extent of progress, people’s livelihood for the development of the cause of our country has made outstanding contribution. In water conservancy construction process, the need to build hydropower stations. For hydropower station, it should not only in the building when the revision of the quality of a degree of assurance, and paid much attention to the maintenance of late. This article mainly aims at the design of hydropower station seismic measures research and analysis. For this study, the selection of a hydropower station somewhere as the research object, the hydropower station seismic intensity of up to 9 degrees. First of all, we to the hydropower station of concrete dam a comprehensive dynamic analysis, in the analytical process, main USES two analysis method, the numerical calculation method respectively and model test method. Through the analysis, we of this hydropower station dam of seismic weak positions were determined and the have a level of understanding, and then based on the actual situation proposed the corresponding design measures.
Keywords: hydropower station; Concrete dam; Seismic research; Fortification intensity

1.引言
本文選取某地的一個(gè)水電站作為相應(yīng)的研究對(duì)象。從水電站自身的角度來(lái)看，此水電站的樞紐建筑物是由多個(gè)部分共同組成的，且具有一定的系統(tǒng)性、連續(xù)性。這些部分主要有碾壓混凝土重力壩、右岸溢洪道、、左岸沖沙底孔以及壩后廠房等。對(duì)于碾壓混凝土重力壩來(lái)說(shuō)，其最高的處達(dá)到了160m。從水電站的周圍環(huán)境來(lái)看，這一水電站處于一個(gè)褶皺帶內(nèi)，因此其所處的地帶具有相對(duì)強(qiáng)烈
