Abstract Abstract：Research purposes： Water supply and drainage system is one of the most important electromechanical systems which security affects the normal operation of the subway system, and affects the safety of life and property of the passenger and the country. In freezing regions of North China, water supply and drainage pipelines in the subway station are subject to injury by frost in winter, so as to affect the normal operation and safe use of the subway. This paper based on the analysis of factors of water pipes freezing in the subway station at the beginning of design, provides a safe and freliable solution of station water pipeline electric insulation design for the reference of those future projects. Research conclusions：(1) It is feasible to use the constant power electric tracing and insulation technology in the metro station entrance in cold areas. (2) The design of subway in cold regions need to be coordinated with the construction and environmental control system. Soil cover depth of station burying properly increasing and adding hot air curtain and other measures can improve the safety of water pipes antifreezing insulation. (3) Selection of materials of the pipeline thermal insulation should be the A-class non-combustible material in subway, adopts the double wire heating cable can improve the reliability of the system. (4) This research provides a model for control mode and the selection of electric insulation system of subway stations, and has a guiding role for the subway operation energy consumption analysis and cost control.
