要約(英語): Power cables are often laid in ducts buried underground of roads. In such installation, there is a possibility of so called cable creepage phenomenon in which cable moves in a direction of traffic flow. This phenomenon may result in abnormal stress on the cable, leading to damage. In order to take effective measures, it is important to accurately evaluate the cable movement force and amount generated by this phenomenon. So far, the cause of this phenomenon has been considered to be the vertical bend of the duct. The authors concluded that the cable creepage phenomenon is essentially caused by the horizontal displacement of the duct due to car loading. In the process of the passing of a car, the impulse due to the friction force acting on the cable is larger in traveling direction of the car than in the opposite direction. This impulse difference is considered to be the cause of the cable creepage phenomenon. Based on this theory, a cable ceepage computing system that can be used with conventional PCs was constructed.
