摘要
Probing into tunnel fractured zones by means of Audio magneto Telluric (AMT) has given evidence that the Zhuangyuanbei-Madao fault (F2) is present in an angle of gentle in the upper part and steep in the lower part and thereafter, drilling has proved the conclusion, indicating that it would be available and effective to use Audio magneto Telluric (AMT) for detecting fractures in tunnel.
