| 中文摘要: |
| 本文基于ANSYS运用三维稳定渗流有限元法对某面板堆石坝进行渗流稳定性分析，研究了渗控措施设计方案下工程的渗流场分布及渗透稳定性，评价渗控措施的有效性，并对混凝土面板和防渗帷幕的渗透系数的变化对大坝渗流场的影响进行模拟。研究结果表明：大坝防渗系统防渗效果较好，有效的控制了坝内渗流场的分布；混凝土面板及防渗帷幕渗透系数的改变对渗流场影响较大，在渗控系统的施工过程中须严格控制施工质量。 |
| 英文摘要: |
| This article is focusing on analyzing the seepage stability of a certain concrete face rockfill dam, by using three dimensional stable seepage finite element method based on ANSYS. Researching the distribution of seepage field and seepage stability about seepage control measures of the engineering design, and the Influence about seepage field of dam seepage field by changing permeability coefficient of concrete face and impervious curtain，evaluating the effectiveness of the seepage control measures. The result of analysis shows that the effect of dam seepage control system is good for Effective controlling the distribution of the seepage field in the dam; the quality of the construction process for seepage control system should be strictly controlled ,because the permeability coefficient of the concrete slabs and anti-seepage curtain have a greater influence on the change of dam body seepage field. |
