摘　　要：文章以周家营水库土坝为例,采用流体力学有限元法计算了瞬态典型工况下的大坝渗流场和大坝典型断面的稳定性。结果表明,坝体边坡稳定系数大于规范允许的安全系数,心墙渗透坡降满足要求,心墙顶高程421.14m,截水槽底宽3.4m,底宽满足规范要求,能够保证坝体渗流稳定性。Taking earth dam of Zhoujiaying reservoir as an example,the stability of seepage field and typical section of dam under transient typical working conditions is calculated by finite element method of fluid mechanics.The results show that the stability factor of the dam slope is greater than the safety factor permitted by the code,the seepage slope of the core wall meets the requirements,the height of the top of the core wall is 421.14 m,the bottom width of the interceptor tank is 3.4 m,and the bottom width meets the requirements of the code,which can ensure the seepage stability of the dam body.
