| Abstract: | Based on the comprehensive survey of abnormal rail corrugation for Beijing Metro Line 4,the characteristics of rail corrugation were figured out.In order to find out the causes why serious corrugations appeared on the shear-type fastening system section,rail initial roughness was evaluated,and rail hardness and the lateral deflections of the shear-type fastening system were measured.Based on the above analysis,the reasons of abnormal rail corrugation due to the shear-type fasteners were identified,and some ... |
