综合物探技术在水工隧洞隐伏缺陷探测中的应用

Application of Comprehensive Geophysical Technology in the Detection of Hidden Defects in Hydraulic Tunnels

为查明某水工隧洞隐伏泥岩富水软化缺陷发育规模,通过研究电磁波、地震波在富水软化泥岩、原状泥岩及衬砌混凝土结构传播过程中的相位、振幅等波动学差异,确定了隐伏富水软化泥岩缺陷发育深度和范围,探测成果得到验证,为缺陷处理方案设计提供了科学依据.

In order to find out the development scale of water-rich softening defects in hidden mudstone of a hydraulic tunnel,the development depth and range of hidden water-rich softening mudstone defects were determined by studying the wave differences of electromagnetic wave and seismic wave in the propagation process of water-rich softening mudstone,undisturbed mudstone and lining concrete structure.The detection results have been verified,providing a scientific basis for the design of defect treatment schemes.
