摘要：
This paper presents a study on the cause and treatment for a special wavelength-fixed rail corrugation developed on Egg fastening system section of certain metro line based on both field and laboratory measurements. Research results indicate that the special rail corrugation developed on Egg fastening system section is closely related to the vertical rail dynamic response of track form. The sensitive point of resonance appears on the vertical dynamic response curve of Egg fastening system section in the frequency range of 180~230 Hz and 250~320 Hz, which agrees well with the exciting frequencies induced by train-track dynamic interaction at the speed of 60 km·h-1, indicating that it is the cause for corresponding wavelength-fixed corrugation. In order to suppress the growth of corrugation, Egg fastening systems are replaced by GJ-III fastening system with the upper iron tie plate directly acting on the rubber pad. Both fastening systems are of similar static stiffness and vibration reduction performance. The train-track dynamic interaction in the range of 180~210 Hz is considerably reduced by the alteration of track dynamic properties. After the observation for almost a year, monitoring data show that the moving average peak to peak amplitude in the wavelength of 30~100 mm is reduced by about 20 μm (maximum).
