为了探讨城市轨道交通长大陡坡在连续提升超过16m的情况下，车辆的制动及电机温升的可行性，通过对城市轨道交通长大陡坡的含义、特点及需要解决的相关问题进行论述，并结合仿真模拟和工程测试等方法，论证了轨道交通长大陡坡在一定的范围内制动影响和电机温升是安全的，并通过深圳4号线试验来验证设计，最终证明了长大陡坡的设计所采用的措施是有效的、科学的。

The signification and characteristics of long steep slope section of rail transit lines, as well as the problems to be solved regarding the long steep slope section, are discussed. Simulation and engineering test made shows that the vehicle brake influence and the electrical motor heating occurring within a certain range of long steep slope section of rail transit lines are safe. The design is verified in the design of No. 4 line of Shenzhen Metro, which demonstrates that the measures taken for the long steep slope section are effective and rational.
