| 摘 要： | 紫坪铺水利枢纽工程右岸条形山脊布置了工程的主要水工建筑物，因此条形山脊的渗流场特性对工程的安全性至关重要。根据坝址工程地质水文条件及防渗处理措施，运用三维有限元方法，研究右岸条形山脊的渗流浸润面，水力坡降以及主要地下洞室的外水压力分布，并对计算域外天然地下水补给防渗帷幕及排水系统的不同施工质量对渗流场特性的影响进行了分析。分析表明防渗处理措施效果明显，并提出了优化建议。

| Abstract: | The main hydraulic structures of Zipingpu Hydro project are arranged in right bank striped mountain ridge. Consequently, the seepage flow characteristics have much influence on the project's stability. Based on hydrogeologic conditions and anti seepage considerations in dam site area, 3D seepage flow finite element method (FEM) is used to study the seepage wetted area, distribution of seepage gradient and seepage pressure of main tunnels in order to analyze the influences on the characteristics of seepage flow field by various anti seepage construction quality, draining system and natural groundwater supply out of calculated area. The analysis shows that anti seepage measures of draining design are effective and optimizing suggestions are put forward. |
