Introduction   Taking shield power tunnel as an example, according to its construction characteristics, the purpose and method of shield power tunnel construction monitoring are systematically analyzed.

    Method   Firstly, the monitoring layout method of tunnel construction in China and the characteristics of power tunnel were combined with, the purpose and scope of monitoring were analyzed, the deformation control standards of surrounding structures and their own structure requirements were obtained; Then, the monitoring method of shield power tunnel construction, the data processing method of management measures, the result submission method and the information feedback strategy were analyzed and put forward in the paper. Combining with the monitoring practice of a shield power tunnel construction, the paper analyzes and demonstrates the monitoring purpose and method.

    Result   Combined with the construction monitoring practice of a shield tunnel, the purpose and method of the monitoring are analyzed and demonstrated.

    Conclusion   The research results provide great significance for the safety and smooth construction of shield power tunnel, and can also provide a reference for other similar projects.
