Abstract: With the continuous changes of social economy, people pay more attention to subway engineering. The subway project is closely related to people's daily life, and its continuous development and improvement can provide convenience for people's daily life and ensure people's safe travel. In subway engineering, it is necessary to use a variety of mechanical equipment, which can provide stable support for the smooth development of subway engineering.Therefore, in the process of subway construction, it is necessary to take practical and effective measures to manage machinery and equipment in order to improve its working efficiency. Based on this, this paper comprehensively summarizes the problems existing in the construction management of metro machinery and equipment, and puts forward reasonable optimization countermeasures in order to further improve the utilization rate of metro machinery and equipment.
