  要:山区高速公路机电设施接地施工较之平原地区困难许多。本文结合山区高速公路机电设施接地常见问题,分析其接地电阻偏高的原因是土壤电阻较高、土层薄,地质条件差、场地狭小,使接地网面积偏小,就山区高速公路隧道机电设施、道路监控设施接地给出了相应的措施。

Abstract: The construction of the highway electrical and mechanical facilities in mountainous area is much more difficult than that in the plain area. In this paperthe reasons of grounding resistance on the higher side was analysed according to the common electromechanical facilities grounding problems in highway mountainous area that, higher soil resistanc, thin soilpoor geological conditionsnarrow space, small ground area and so on. Finally,corresponding measures were put forward for the mountainous area highway tunnel mechanical and electrical facilities and road monitoring facilities grounding.
