Research on Stress-Free Rail Temperature Design of Wubei-Xiaohuangshan Railway

Abstract:

Wubei-Xiaohuangshan railway was characterized by the large local temperature difference, and high density of heavy haul train traffic. Reasonably determining the rail stress-free temperature has an important role on the line traffic safety and stability. Combined with the actual situation of the line, this paper researched some key technical issues of laying CWR in alpine and large temperature difference region, from determining the reasonable allowable temperature rise, allowable temperature drop, the rail stress-free temperature, and its allowable ranges, etc. Look forward to give some reference to the similar engineering problems.
