Abstract: With the expansion of the scale of China's power grid, there are more and more power tunnel projects. In the implementation of such projects, the technical difficulty is higher, and there are many security risks. If there is no whole process and all-round security management, it will increase the operation risk of power network and aggravate the occurrence of power security accidents. Therefore, when participating in the construction of power tunnel engineering, engineering enterprises should follow the relevant provisions of safety management and eliminate various potential safety hazards on the construction site through the application of various safety measures. Based on this, this paper focuses on the safety management measures of power tunnel, which is helpful to guide the actual construction and improve the project benefi ts.
