A brief analysis of the power cable planning and design of the utility tunnel

The urban utility tunnel plays an important role in improving the utilization efficiency of urban underground space. With the vigorous promotion of the construction of urban utility tunnel, the scale of power cable into urban utility tunnel is also increasing rapidly. There are some problems in the planning and design process of utility tunnel, such as the lack of technical specifications or the inconsistency of existing standards and norms. Thus, some detailed design requirements of the overall design, section design and ancillary system design of the power pipeline are proposed in this paper, especially the details of the power cables entering into the utility tunnel are discussed in detail, providing a reference for other engineering. It would be helpful for the electric power cables entering into the utility tunnel in the future.
