The electromechanical equipment in underground utility tunnels plays a crucial role in ensuring the smooth operation of urban functions, and its seismic performance is vital to the safety of the city. In the face of frequent earthquakes, enhancing the seismic performance of electromechanical equipment has become an urgent issue to address. This article delves into the structural damage, connection failure, and pipeline rupture issues faced by electromechanical equipment during earthquakes. It proposes optimization strategies from multiple aspects, including structural design optimization, connection method improvement, and material selection upgrade. The application of seismic resistance technology in electromechanical equipment, such as the use of seismic isolation and shock absorption techniques, is elaborated. A comprehensive seismic performance evaluation system is constructed, encompassing earthquake simulation testing and practical case analysis. Through a series of measures, we aim to significantly enhance the seismic performance of electromechanical equipment in underground utility tunnels, providing a solid guarantee for the safe and stable operation of urban infrastructure.
