摘要：
The tunneling construction in underground DC Metro Systems is mainly based on the bored tunnel method and the cut-and-cover method. Therefore, the stray current assessments and mitigation actions should be tailored according to which method of tunnel construction is used. This paper presents a topologically accurate model for assessing the dynamic stray current picture in cut-and-cover sections of DC metro systems. The dynamic stray current evaluation can provide an indication to the extent of the corrosion problem in the supporting and third-party infrastructures of the system. In this paper, the dynamic evaluations are based on a combination of various ideal and realistic train operation scenarios.
