摘　　要： 通过风田水库坝体实测浸润线与由注水试验成果计算的理论浸润线对比,分析认为注水试验取得的渗透参数需进行修正。采用修正后的渗透参数对坝体进行稳定渗流及非稳定渗流计算,计算结果与实际情况相符,得出坝体安全鉴定渗流安全评价结论为:主坝各工况下出口坡降小于允许渗透坡降,满足规范要求。 For Fengtian Reservoir,the measured infiltration line of main dam was compared with the theoretical infiltration line calculated according to the results of water injection test,based on which it is put forward the permeability coefficient out of water injection test needs to be corrected.Steady seepage and unsteady seepage calculation of main dam were made with the corrected coefficient.The results of calculation are consistent with the actual situation.The seepage evaluation conclusion of dam body safety assessment is the main dam exit gradient is below the permissible seepage gradient,conforming to the requirements of specifications.
