For rational development and comprehensive utilization of urban underground space, improve the utilization rate of urban highway tunnel, it is considered to lay power cables on the basis of built tunnels. However, there are certain hidden risks. Therefore, the following research is carried out to identify and implement corresponding protection measures for risks: first, the structural composition of the cable tunnel is analyzed, meantime, the safety risk events of the historical cable tunnel are studied, and then the various risk sources existing in the laying of the power cable system using the built tunnel are identified. Based on this, the corresponding protective measures are put forward in order to improve the reliability of the cable laid in the existing tunnel.
