随着信息化的迅速发展,像地面智能化建筑一样,许多隧道工程也安装了智能化控制、数字化管理系统,有的甚至还具有数据中心的功能。而这些设备与系统的正常运行需要安装在性能良好、可靠的接地系统之上。同时,可靠的接地系统也是保障相关操作人员人身安全的基本要求。因此,在工程的设计与施工过程中,接地系统是非常重要的。根据隧道工程的特点,探讨了隧道工程自然接地体接地电阻值的计算方法,主要包括围护结构与支护锚杆等接地电阻值的计算。
With the rapid development of information technology, like the intelligent building on the ground, many tunneling projects have also installed intelligent control and digital management systems, and some even have the functions of data centers. The normal operation of these devices and systems needs to be installed on a well-performing and reliable grounding system. At the same time, a reliable grounding system is also the basic requirement to protect the personal safety of the relevant operators. Therefore, in the design and construction of the project, the grounding system is very important. According to the characteristics of the tunnel project, the calculation method of the grounding resistance value of the natural grounding body of tunnel engineering is discussed, including the calculation of the grounding resistance value of the envelope and the supporting bolt.
