| Abstract: | Karst caverns and faults around the railroad present a great threat to the safety of railroad tunnel construction. In this paper, the authors explored applicability of the high frequency MT method by using the stratagem EH -4 electrical conductivity image -forming system for advance detection of the karst caverns and faults within a specified depth. At the end of the paper a case study is presented to demonstrate its application. |
