【摘要】：路俄水庫工程位于云南省紅河州綠春縣境內(nèi),位于綠春縣西部�？缀拥闹Я鞴ê由�,屬紅河水系。路俄水庫工程等別為Ⅲ等,工程規(guī)模為中型,是一宗以城鎮(zhèn)、農(nóng)村人畜生活供水和農(nóng)業(yè)灌溉為任務(wù)的水利工程。本文主要對(duì)水庫工程的擋水建筑物礫石土心墻堆石壩進(jìn)行設(shè)計(jì),土石壩設(shè)計(jì)的關(guān)鍵在于能否在滲流作用下滿足邊坡穩(wěn)定。主要成果如下:(1)根據(jù)水文地質(zhì)等資料,確定壩型選擇、工程布置等。通過計(jì)算確定壩頂高程等壩體尺寸數(shù)據(jù)。(2)根據(jù)水文資料,進(jìn)行興利調(diào)節(jié)計(jì)算和洪水調(diào)節(jié)計(jì)算,確定水庫死水位、正常蓄水位、設(shè)計(jì)洪水位、校核洪水位等水庫特征值以及水庫工程規(guī)模。(3)根據(jù)確定的壩體尺寸,進(jìn)行CAD繪圖,將其導(dǎo)入理正軟件開始建模,輸入相應(yīng)計(jì)算參數(shù)完成建模。根據(jù)工程地質(zhì)報(bào)告確定相應(yīng)的計(jì)算參數(shù)。理正軟件的計(jì)算結(jié)果顯示大壩滲流穩(wěn)定與壩坡抗滑穩(wěn)定均滿足規(guī)范要求。(4)對(duì)Geo-studio軟件進(jìn)行了介紹,并在Geo-studio軟件的Seep/w模塊和Slope/w模塊進(jìn)行建模,計(jì)算參數(shù)與理正軟件相同。計(jì)算得出單寬滲流量、下游逸出比降、抗滑穩(wěn)定安全系數(shù)等。(5)兩款軟件所計(jì)算出的抗滑穩(wěn)定安全系數(shù)雖有差異但在合理范圍之內(nèi),可用于大壩安全性評(píng)價(jià)。結(jié)合規(guī)范給出的壩坡抗滑穩(wěn)定最小安全系數(shù)得出結(jié)論本文的土石壩設(shè)計(jì)完全滿足滲流穩(wěn)定和壩體邊坡穩(wěn)定。
[Abstract]:Luo Reservoir Project is located in Luchun County, Honghe Prefecture, Yunnan Province. It is located on the Haka River, a tributary of Niukong River in the west of Luchun County, and belongs to the Red River system. The Luo Reservoir Project is a water conservancy project with the task of water supply and agricultural irrigation for urban, rural people and livestock, and the scale of the project is medium-sized. In this paper, the gravel core wall rockfill dam of reservoir engineering is designed. The key to the design of earth-rock dam lies in whether the slope stability can be satisfied under the action of seepage. The main results are as follows: (1) according to the hydrogeological data, the dam type selection, engineering layout and so on are determined. The dam size data such as dam top elevation are determined by calculation. (2) according to hydrological data, Xingli regulation calculation and flood regulation calculation are carried out to determine reservoir dead water level, normal water level, design flood water level, check flood water level and reservoir engineering scale. (3) according to the determined dam body size, CAD drawing is carried out, which is introduced into correction software to start modeling and input corresponding calculation parameters to complete modeling. The corresponding calculation parameters are determined according to the engineering geological report. The calculation results of the correction software show that both the dam seepage stability and the dam slope anti-slide stability meet the requirements of the code. (4) the Geo-studio software is introduced and modeled in the Seep/w module and Slope/w module of the Geo-studio software, and the calculation parameters are the same as those of the correction software. The single width seepage rate, downstream escape ratio drop, anti-skid stability safety factor and so on are calculated. (5) although the anti-skid stability safety factor calculated by the two software is different, it can be used for dam safety evaluation within a reasonable range. Combined with the minimum safety factor of anti-slide stability of dam slope given by the code, it is concluded that the design of earth-rock dam in this paper fully satisfies the seepage stability and dam slope stability.
