Abstract

Water channel detection has become the focus and difficulty of tunnel detection because of needing a higher resolution. We put forward the array antenna source transient electromagnetic tunnel detection method on the basis of radar array antenna. Firstly, it verifies that the array antenna source has better recognition ability than small loop and tests the advantages of horizontal component than vertical component of water-bearing geologic structure detection. Influence of array transmitter scale, source length and source spacing on different components of the transient electromagnetic data is analyzed, and concludes the influence of the distance between fault and tunnel surface, thickness of the fault, the fault and surrounding rock resistivity difference and other parameters of the response characteristics under the same antenna array source
