Based on the geological and hydrogeological conditions of upper and lower reservoirs of a pumped storage power station, the three-dimensional numerical simulation model of dam was established by using ADINA finite element software. The distributions of seepage and seepage field of upper and lower reservoirs under various operating conditions were calculated and analyzed. Under the condition of changing the water level of the upper reservoir, the variation law of the seepage parameters in the reservoir water level is analyzed, and the change of the free surface of the dam is calculated. The water level decreases, such as the head line, the infiltration line and seepage flow. It is concluded that the seepage flow is decreasing but the infiltration line remains essentially unchanged during the descent of the water level.","PeriodicalId":349946,"journal":{"name":"Journal of Water Resources Research","volume":"16 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123510053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, based on the combination of particle swarm optimization and finite element method, the average depth and equivalent thickness of impervious curtain under the constraint condition were calculated for concrete face rock fill dam on deep overburden. Firstly, the seepage field of the dam foundation in the 2D model was analyzed, and the permeability of the dam foundation is relatively high when it has no curtain, and it is easy to produce osmotic rupture. It is therefore necessary to perform grouting in the bedrock to reduce dam foundation seepage. The particle swarm optimization (PSO) is feasible and applicable in the optimization of curtain structures. It is concluded that as the number of iterations increases, the particles are close to the optimal solution, and the objective function (engineering cost) is gradually reduced and tends to be gentle as the number of iterations increases.
