| 摘 要： | 本文论述了钻孔揭露裂隙岩体与裂隙斜交情况下通过示踪方法测定裂隙渗透性及其参数，将稀释测井与示踪测井方法相结合建立了井流理论。推导了双井系统中单裂隙岩体的渗透系数、等效水力隙宽、静水头、影响半径及水力坡度等的计算公式，并将此研究成果应用于大坝的渗流场探测之中。

| Abstract: | An isotope tracer method for detecting the permeability and its parameters of fissured rock in borehole is presented in this paper.Based on the combination of dilution logging and tracer logging methods the flow principle is established.The formulas for calculating the permeability coefficient,equivalent mechanical fissured rock width,static water level,reference radius and hydraulic gradient of the coupled well system are proposed. |
