基于线路伤损的大轴重货车经济性评价

Economic evaluation of heavy axle-load wagons based on railway-line damage model

运用大轴重货车开展重载运输是一项庞大的系统工程。借鉴国外重载运输经济性的相关研究成果,从大轴重货车运用对线路、桥梁的伤损模型入手,结合重载运输经济性的具体案例,研究大轴重货车运用的经济性问题。

Adapting heavy axle-load wagons in heavy-haul transportation is a comprehensive system engineering. Ac- cording to the results of heavy-haul transportation in other countries, the author researches the issue of economic benefits in heavy axle-load wagons based on the damage model on rail and bridges. Meanwhile, the author gives an illustration of analysis on heavv-haul transportation economic benefits to prove his issue.
