정적과 동적 궤도검측결과에 관한 연구

To find the causes of the derailment, measurement of track irregularity is necessary. Track measurement should be performed by using track measurement vehicles, however, deploying those vehicles to the sites where the accident has occurred is almost impossible. Trolley type measurement equipment is used instead in these cases. But the weight of the trolley type equipment is less than one hundred kilograms so the effect of the wheel load from the actual railway vehicles to the track cannot be reflected. In this paper the test results from the different track measurement equipment are compared and proposed to reflect the results to the track maintenance criteria.
