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。
The isotope tracer method was used to study the seepage field of fractured rock mass in Xinanjiang right dam. The isotope tracer technique can be used to obtain the hydraulic parameters such as flow velocity, flow direction and vertical flow in a single hole. Based on the related groundwater flow theory, the equivalent hydraulic gap width and the permeability coefficient can be calculated to reflect the fracture permeability The parameters, which are analyzed, determine the distribution of the seepage field and the location of the concentrated leak path.
