大饭铺至马栅铁路长大下坡道取值分析研究

Analysis and Study on Value Range of Long Steep Down Grade on Dafanpu-Mazha Railway

从大饭铺至马栅铁路运输组织方式及限制坡度方案角度分析如何保证重载货物列车在长大下坡道的运行安全,并根据《列车牵引计算规程》和《铁路技术管理规程》等规定提出长大坡道取值的计算方法。最后按照周期制动的原理进行实例计算,确定大马铁路的合理下坡道取值方案。

This paper analyzes how to ensure the operation safety of heavy-haul freight trains on long steep down grade from the view of transport organization mode and limiting gradient program on Dafanpu-Mazha railway. The paper also puts forward the calculation method of value range of long steep down grade according to Regulations of Train Traction Calculation and Regulations of Railway Technical Management. In the end, the example calculation is taken according to the principle of cycle braking, and the reasonable value range program of long steep down grade on Dafanpu-Mazha railway is determined.
