水库渗漏通道的伪随机流场法与双频激电法综合探查
|
摘要
正确快速的探测水库堤坝渗漏在保证防洪工程安全上具有重要意义,而查明渗漏入口和渗漏途径又是难点中的重点,本文简述了伪随机流场法的基本原理,重点探讨了当水库坝体中存在诸多金属管,且渗漏水为承压水形式时,传统流场法难以解决实际问题时,作者首先采用流场法对水库大坝进行电流场分布的检测后,再结合双频激电法,详细的分析和对比检测的数据,从得到的探测曲线分析表明,通过流场法与双频激电法的结合,极大地提高了流场法区分金属管和地层渗漏通道的能力,为以后的相关工程应用提供了很好的范例.
Fast and correct leakage detection plays a vital role in the safety of reservoirs and precisel detection of leak-holes and leak-paths is always the difficulty and also the key point in this aspect.This paper after illustrates the basic principle of the pseudorandom flow-field method, and focuses on the problem of distinguishing the metal pipe and stratigraphic leak-paths when the seepageis in form of pressure water, which brings great challage to the traditional psuedorandom flow-field method.We measure the distributed electric field of the reservoir using DFIP (Dual frequency induced polarization) method, and analyse the detected data and curves.The application shows that this combination method is feasible and the ability of distinguishing the metal pipe and stratigraphic leak-paths is highly enhanced.
