【摘要】：羊倌溝水庫位于青海省西寧市樂都區(qū)高廟鎮(zhèn)保家莊村附近，是一座IV等小（I）型攔河式水庫，組成水庫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級建筑物標準設計，次要和臨時建筑物級別為5級。其主要功能是以人畜飲水、農田灌溉為主，兼顧防洪。 羊倌溝水庫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、造價低、節(jié)約大量水泥、鋼材、能適應較差的地質條件、安全性能好等優(yōu)點，，在國內工程中被廣泛的使用。但目前土石壩設計工程中，仍大多采用傳統(tǒng)的設計方法，其設計仍處于經驗階段，而且在小型水庫設計過程中,不太注重設計總體方案的優(yōu)化。 本文在依據(jù)水庫基本水文資料及地質條件，對水庫進行了供水規(guī)劃和調洪演算，確定了水庫規(guī)模，完成了水庫樞紐布置及擋水建筑物的主要設計工作，利用ANSYS軟件對面板壩進行了滲流穩(wěn)定分析和應力變形分析。對水庫整個設計工作完成兩個方面的優(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)化是在水庫規(guī)模不變的情況下，討論了在抬高水庫汛限水位的同時增大水庫溢洪道規(guī)模，在兩者之間追求水庫效益最大化；壩體斷面的優(yōu)化是用ANSYS建立壩體模型的基礎上，在面板壩結構類型、材料布局已定的情況下，采用造價最低的原則，通過利用數(shù)學手段和ANYSY有限元分析軟件，來獲得結構斷面的最優(yōu)尺寸，兩者均有比較重要的現(xiàn)實意義。
[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.
