【摘要】 为满足大坝坝基水文工程地质及帷幕工况检测的要求,提出了一种新的方法技术——伪随机流场法测井,介绍了该方法的基本原理.针对四川铜街子水电站坝基检测工作介绍该方法的异常特征,该方法检测的结果与传统波速测井、钻孔电视以及压水试验等方法结果进行了对比分析,表明该方法是有效可行的,并能提供比传统单一方法更多的信息.更多还原

【Abstract】 A new technology\|Psuedorandom Flow\|field Method Logging (PFML) is introduced,which can be applied to detecting the dam foundation such as hydrological\|engineering geology and curtain condition. We adopted this method in the detecting work of Sichuan Tongjiezi hydroprower station dam foundation, the character of PFML has been analyzed. PFLM is also contrasted with the traditionary method such as wave velocity logging, borehole televiewer and pumping\|in test in this paper. The contrastive results show that PFML is effective detecting method for dam foundation, which can provide much more information than traditionary method.更多还原
