Abstract and Keywords

Abstract: The natural seepage recharge of Yufu River in the west of Jinan plays an important role in maintaining the spout of spring water of Baotu Spring, and the Dongkema-Cuima section is the strong seepage zone of Yufu River. In this paper, COMSOL software was used to simulate the groundwater flow field of the strong seepage zone of Yufu River. According to the three scenarios of the maximum (40 m) and minimum (25 m) buried depth of average groundwater level of the strong seepage zone and the buried depth of groundwater level between them (30 m), the recharge scheme to avoid ineffective replenishment was obtained; when the groundwater buried depth was 25 m, a recharge rate of $ 18.01 \times 10^{4} $ m $ ^{3} $/d was used for continuous recharge for about 13 d; when the groundwater buried depth was 30 m, a recharge rate of $ 21.15 \times 10^{4} $ m $ ^{3} $/d was used for about 16 d; when the groundwater buried depth was 40 m, a recharge rate of $ 25.92 \times 10^{4} $ m $ ^{3} $/d was used for about 20 d. The research results provide a basis for the formulation of scientific and efficient recharge plan.

摘要和关键词

摘要: 济南西部玉符河的自然渗漏补给对维持趵突泉的泉水喷涌起到重要的作用, 其中东渴马至催马段为玉符河的强渗漏带, 文章利用 COMSOL 软件对玉符河强渗漏带地下水流场进行数值模拟, 针对强渗漏带平均地下水位埋深最大 (40 m)、最小 (25 m) 以及水位埋深处于两者之间 (30 m) 3 种情形, 得出避免无效补给的回灌方案如下: 当地下水埋深为 25 m 时, 以 $ 18.01 \times 10^{4} \, m^{3}/d $ 的回灌量连续回灌约 13 d; 当地下水埋深为 30 m 时, 以 $ 21.15 \times 10^{4} \, m^{3}/d $ 的回灌量连续回灌约 16 d; 当地下水埋深为 40 m 时, 以 $ 25.92 \times 10^{4} \, m^{3}/d $ 的回灌量连续回灌约 20 d。研究结果可为制定科学高效的回灌计划提供依据。
