寒冷地区无缝线路试验段轨道状态的评判——模糊综合评判原理的应用

Evaluation of the Results of CWR Track Experiment in Severely Cold Territories-Comprehensive Judgment with the Principle of Fuzzy Sets

为在寒冷地区(最大轨温幅度超过90℃)推广应用无缝线路,曾在长大线试铺32km试验段,系统检测了各项表征无缝线路的稳定性和强度的轨道状态参数,运用模糊综合评判原理,对试验段的轨道质量作了评判,并进而分析寒冷地区推广应用无缝线路的可行性。

For the application and development of continuously welded rail track laid in the severely cold territories (maximum difference of rail temperature at the area is over 90C), a testing section of 32km of CWR track at Chang-Da Line was established. A series of testing data about the stability, strehgth and other phenomena of the track were obtained. By application of the principle of fuzzy sets, the quality of the track was analyzed and evaluated in order to determine whether the CWR track is proper to be used in the severely cold territories.
