Abstract: Under the background of continuous economic development in various regions of our country, the subway has become an important rail transportation tool in the city, which can fully reduce traffic pressure, display unique urban functions, and effectively improve the urban ecological environment. The subway is a new product of the economic era and a sign of social progress. Therefore, when designing the ground building of a subway station, it is necessary to have a correct attitude and introduce cutting-edge concepts and new technical ideas in order to create a safe, comfortable and beautiful ground building space for passengers. This paper analyzes the modern design principles around the ground construction design issues of subway stations, and focuses on the technical characteristics of ground design, hoping to provide reference suggestions for subway station designers.
