Jinan rail transit takes "green subway" as the construction concept, and has adopted nearly 40 technical measures to save energy, land, water, materials and environment. This paper mainly takes Line 1 as an example to introduce in detail the land saving technologies such as equipment housing under the elevated station and resource sharing of the main substation, which can save about 28,000 square meters of land. The construction technology of exposed concrete in the elevated station, the prefabricated composite structure system and other material saving technologies can save 30 million yuan and 43% of the concrete usage. By adopting energy-saving technologies such as adjustable ventilated platform door system, each station can save about 1 million yuan of electricity per year. Using photovoltaic power generation on elevated platforms, amorphous alloy distribution transformers, renewable energy absorption and other technologies, it can save 7.7403 million kilowatt-hours of electricity per year. It is expected to provide reference for the construction of Jinan railway line and other urban rail transit.
