【摘要】：羊倌溝水庫(kù)位于青海省西寧市樂(lè)都區(qū)高廟鎮(zhèn)保家莊村附近，是一座IV等�。↖）型攔河式水庫(kù)，組成水庫(kù)樞紐的主要建筑物有：擋水壩、溢洪道、輸水管和沖砂管。主要建筑物按4級(jí)建筑物標(biāo)準(zhǔn)設(shè)計(jì)，次要和臨時(shí)建筑物級(jí)別為5級(jí)。其主要功能是以人畜飲水、農(nóng)田灌溉為主，兼顧防洪。 羊倌溝水庫(kù)擋水壩采用混凝土面板堆石壩，土石壩由于其就地取材、施工方便、工期短、造價(jià)低、節(jié)約大量水泥、鋼材、能適應(yīng)較差的地質(zhì)條件、安全性能好等優(yōu)點(diǎn)，，在國(guó)內(nèi)工程中被廣泛的使用。但目前土石壩設(shè)計(jì)工程中，仍大多采用傳統(tǒng)的設(shè)計(jì)方法，其設(shè)計(jì)仍處于經(jīng)驗(yàn)階段，而且在小型水庫(kù)設(shè)計(jì)過(guò)程中,不太注重設(shè)計(jì)總體方案的優(yōu)化。 本文在依據(jù)水庫(kù)基本水文資料及地質(zhì)條件，對(duì)水庫(kù)進(jìn)行了供水規(guī)劃和調(diào)洪演算，確定了水庫(kù)規(guī)模，完成了水庫(kù)樞紐布置及擋水建筑物的主要設(shè)計(jì)工作，利用ANSYS軟件對(duì)面板壩進(jìn)行了滲流穩(wěn)定分析和應(yīng)力變形分析。對(duì)水庫(kù)整個(gè)設(shè)計(jì)工作完成兩個(gè)方面的優(yōu)化：即總體方案的優(yōu)化和壩體斷面的優(yōu)化，總體方案的優(yōu)化是在水庫(kù)規(guī)模不變的情況下，討論了在抬高水庫(kù)汛限水位的同時(shí)增大水庫(kù)溢洪道規(guī)模，在兩者之間追求水庫(kù)效益最大化；壩體斷面的優(yōu)化是用ANSYS建立壩體模型的基礎(chǔ)上，在面板壩結(jié)構(gòu)類型、材料布局已定的情況下，采用造價(jià)最低的原則，通過(guò)利用數(shù)學(xué)手段和ANYSY有限元分析軟件，來(lái)獲得結(jié)構(gòu)斷面的最優(yōu)尺寸，兩者均有比較重要的現(xiàn)實(shí)意義。
[Abstract]:Yanghuigou Reservoir is located near Baojiazhuang Village, Gaomiao Town, Ledu District, Xining City, Qinghai Province. It is a type of block type reservoir. The main buildings that make up the reservoir hub are: dam, spillway, water pipe and sand pipe. Main buildings are designed according to grade 4 building standard, and secondary and temporary buildings grade 5. Its main function is to drink water, farmland irrigation, flood control. The dam of Yanghuigou Reservoir adopts concrete face rockfill dam. The earth-rock dam has the advantages of easy construction, short construction period, low cost, saving a large amount of cement and steel, being able to adapt to poor geological conditions, and good safety performance, etc. It is widely used in domestic engineering. But at present, the traditional design method is still used in the design of earth-rock dam, and its design is still in the stage of experience, and in the process of the design of small reservoirs, little attention is paid to the optimization of the overall design scheme. Based on the basic hydrological data and geological conditions of the reservoir, the water supply planning and flood dispatching calculation of the reservoir are carried out in this paper, the reservoir scale is determined, and the main design work of the reservoir hub layout and water retaining structure is completed. The seepage stability analysis and stress deformation analysis of concrete face dam are carried out by ANSYS software. The whole design of the reservoir is optimized in two aspects: the optimization of the overall scheme and the optimization of the section of the dam. This paper discusses how to increase the scale of the reservoir spillway while raising the flood limit water level of the reservoir, and to pursue the maximum benefit of the reservoir between the two. The optimization of the dam section is based on the establishment of the dam body model by ANSYS, and the structural type of the face slab dam. When the material layout has been determined, the principle of lowest cost is adopted to obtain the optimal size of the structural section by means of mathematical means and ANSYS finite element analysis software. Both of them have important practical significance.
