摘　　要：放射性同位素测井技术测定含水层水文地质参数的方法目前广泛应用于水利、水电、建筑、铁路等方面。放射性同位素测井技术测定含水层水文地质参数的方法经过国内外大量资料证明是准确可靠的,是一种先进的水文地质勘察手段,也是水文地质测试技术的发展方向。本文以金沙江乌东德水电站为例说明该技术在河床深厚覆盖层渗透系数测试中的应用方法与可靠性。The radioisotope logging technique which could be used to test the hydrogeological parameters of aquifer is widely applied to many fields such as the water conservancy, construction engineering and railway engineering. The technique is proved to be reliable and exact to test the hydrogeological parameters of aquifer. It is the advanced hydrogeological investigation method and it is the progress direction for the hydrogeological testing. Taking the Wudongde Hydroelectric Power Station as the example, the application and the reliability of the technique to the testing of the coefficient of permeability for the overburden layers of riverbed are explained.
