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 method of radioisotope logging to determine hydrogeological parameters of aquifer is widely used in water conservancy, hydropower, construction, railway and so on. The method of radioisotope logging to determine the hydrogeological parameters of aquifers has been proved to be accurate and reliable by a large amount of data both at home and abroad. It is an advanced means of hydrogeological survey and also the development direction of hydrogeological testing technology. This paper takes Wudongde Hydropower Station in Jinsha River as an example to illustrate the application method and reliability of this technology in the test of permeability coefficient of deep overburden in riverbed.
