velocity of groundwater flow
d ixioshui!iUsu地下水流速(veloeity of groundwater flow) 地下水在含水层中的运动速度。地下水运动具有方向性，在平面图上，它垂直于地下水等水位线或等水压线。地下水流速有渗透流速和实际流速两种。 渗透流速一种假想的渗透水流速度。渗透流速表达式为: Q V~止冬 A式中V为渗透流速(又称达西渗透流速)，m/d;Q为通过断面的地下水流量，m3/d;A为垂直于水流的过水断面积，m“。 实际流速地下水在含水层空隙中的实际流动速度。面积孔隙度和总的水流路径的概念如图所示。由于含水层空隙的大小和形状的不同，水流所受阻力也有差别，所以水流在含水层中不同位置的实际流速是不等的。实际流速可用于分析地下水在含水层中运动的性质，而不能用于定量计算。在供水水文地质勘寨中，多用平均实际流速作为判别水流运动状态和定量的指标。地下水平均实际流速是通过含水层过水断面的流量除以过水断面上孔隙的面积，即 Q u~蔽式中二为平均实际流速，m/d;n为孔隙度，%。地下水平均实际流速与渗透流速的关系为:，一孔隙空间中的 尹产~~~一-一-甲，州擞、‘己介注断义买际水流路径卜衬><尹飞刁l孔隙面积.曰生乙占.占幽‘拓佑益~~人了、代产气卜妇卜~一~门产们A.夕气味和翻丫从了州\l、傲\平也登的 脚，丫~b 面积孔隙度和总的水流路径约概念 a一面积孔隙度;b一总的水流路径 V U二二— n 平均实际流速又有称做平均孔隙流速的。有时即使是在均质流体中，孔隙中的一部分流体仍是不动的，如细颗粒介质中被吸附或部分盲端孔隙中被阻滞水流，因此对渗透水流来说，公式中需用有效孔隙度来表征，即 Q “一石厕式中从f为有效孔隙度(
