| 摘 要： | 应用同位素示踪方法对新安江右坝的裂隙岩体渗流场进行了研究。在单孔中应用同位素示踪技术可得到流速、流向、垂向流等水力学参数,结合相关的地下水井流理论,就可计算出裂隙等效水力隙宽、渗透系数等反映裂隙渗透性的参数,对其进行分析,就确定了渗流场的分布以及集中渗漏通道的位置。

| Abstract: | The fissured rock seepage flow field of Xinanjiang river right dam is studied by using the isotope tracer method.Such hydraulic parameters as flow velocity,flow direction and vertical flow can be obtained with the isotope tracer technique in single boreholes.The coefficients reflecting the permeable characteristics of fissure such as seepage coefficient,equivalent mechanic fissure width etc.are obtained combining with related seepage theories.The distribution of seepage field and the location of concentrated seepage passage are determined by analyzing these coefficients. |

| Keywords: | fissure seepage passage isotope tracer |
