摘要
用放射性同位素^(131)测定沁河冲洪积扇深部含水层的渗透系数,并通过抽水时和抽水后渗透速度与流向的测定,确定了对岸抽水孔的影响状况。
The permeability coefficient of deep aquifer at Xinhe alluvial fan is determined by radioactive isotope^(131)I. The seepage velocity, and direction during and after pumping are determined. Thus, the influencing conditions of the pumping hole at the opposite bank are ascertained.
