摘　　要：从母线、配电电缆、架空线三方面,介绍了隧道供配电导体截面的选择方法,探讨了温度、土壤热阻率、海拔高度等环境因素对载流量影响的校正系数,旨在降低公路隧道供配电线路的电能损耗。From busbar, distribution cable and overhead line, the paper introduces the selection methods for the power supply and distribution conductor section of tunnels, explores the influence of the environmental factors including temperature, soil thermal resistivity, elevation on the correction coefficient of the carrying capacity, so as to lower the power consumption of the power supply and distribution line of roads and tunnels.
