Abstract

Based on the research on a number of small radius curves (R=200m) for the heavy-duty traffic between the I and II inter-fields in the port operation area of the Huanghua Port Station of the Huangzhou-Hongzhou Railway, this paper describes the various diseases of small radius curves under heavy loading conditions, mainly including frequent problems such as large gauge, serious damage of spare parts, deviation of sleeper, extrusion damage of sleeper shoulder and rail abrasion, etc. Through the summary of the laws and causes of various diseases, combined with a variety of measures to carry out the practice of small radius curve disease remediation, the application of the new special concrete sleepers has fundamentally effectively solved various diseases in the operation of small radius curves. The maintenance period has been extended, and the safe operation reserve of the small radius curve of the Huanghua Port Station of the Huanghuang Heavy Railway has been increased.
