摘要
为研究国家森林公同规划水域的渗漏量问题，进行了现场渗透试验。结果表明，渗漏量随着时间的增长而减小，无侧渗试验的渗透速度从试验开始的2．68m／d下降到结束的0．24m／d；有侧渗试验的渗漏量从试验开始的22．08m3／d下降到结束的13．200／d。经计算，规划人工湖初期30d的渗漏量在98．27×10^4-142．93×10^4m^3之间。进入稳定期后，估算渗漏量每年不超过100×10^4m^3。
To study man-made lake＇s leakage in national forest park, the seepage experiment on site is accomplished. The leakage is decreased with time past. The velocity of seepage with no lateral seepage is decreased from 2.68m/d to 0.24m/d for whole test period; the seepage with lateral one is decreased from 22.08m^3/d to 13.20m^3/d. It is estimated that the seepage of man-made lake in early 30 days will be in the scope of 982,700m^3 to 1,429,300m^3 . The seepage will be less than 1,000,000m^3 per year after it is entered into stable period.
