摘　　要：为保证隧道电缆在施工、运营过程顺利进行,减少温度变化产生的热机械力、交变电流产生的感应电压等不利因素,对隧道内部电缆布置方案进行方案设计,其中包括电缆隧道截面布置、电力电缆敷设方式、隧道交接处布置方式。研究表明,在有条件的前提下,单芯电缆布置方式采用"品"字形、金属护套接地方式采用"品"字形双端接地形式的安全性较好;隧道内敷设方式采用垂直蛇形敷设能合理利用空间。In order to ensure the success of cable laying in tunnels during the construction, reduce the disadvantages of thermal stresses due to temperature fluctuation and induced voltage by alternating current, the design of cable laying in internal tunnel is introduced in this paper, including the arrangement of cable in tunnel cross-section, the laying method of power cables, and the arrangement in tunnel junctions. The research results indicate that it is safer to adopt ＂ Pin （Chinese word）＂ glyph for the distribution of cable with single core and the double-ends grounding method of metal sheath. And the serpentine layout in internal tunnel benefits the reasonable using of space.
