Abstract
In a duct system, which is an underground cable laying system, a phenomenon called cable creepage phenomenon may occur in which the cable ac米兰中国官网 duct moves ac米兰中国官网 traveling direction of the vehicle. If this phenomenon progresses excessively, there is a concern that serious damage may occur ac米兰中国官网 vicinity of the cable joint. It is necessary to accurately grasp the moving force of the cable to solve for the phenomenon. However, ac米兰中国官网 past, studies using empirical formulas were mainly adopted, and there was a discrepancy with the actual result.
For this reason, in this research, we focused on the horizontal displacement of the duct when a vehicle passes through it, and developed a new theory using the behavior of the displacement difference between the cable and the duct at that time. In addition, an analysis system for the creepage using the theory was developed. In order to confirm the validity of the theory, we conducted a full-scale experiment and compared the experimental values with the theoretical values to reconcile the two.
