线路节能坡设计方案对地铁能耗的影响

在地铁运营支出费用中，电能消耗费用占到很大比例。在地铁建设时期，通过合理利用节能坡的理念进行线路纵断面的设计，可以有效降低牵引能耗值，大大节省运营支出。此文着重就线路纵断面节能坡的设计与列车运行及列车能耗的关系进行比较与分析。

Impacts of line's energy saving slope design scheme on energy consumption of metros

Of the metro's operating cost,electric energy consumption makes up a large proportion.In the period of metro construction,should the vertical alignment design be taken with the concept of making a reasonable use of the energy saving slope,the value of traction energy consumption could be effectively reduced to greatly economize the operating expenditure.This article performs a comparison and analysis of the relationship between the energy saving design of vertical alignment and train operation and energy consumption of the train.
