Abstract
Urban rail transit is an important hub of urban transportation,which bears the great responsibility of transportation.With the social and economic development,the original subway station is difficult to meet the demand of transportation,so it is necessary to carry out corresponding construction.As far as the subway station construction is concerned,there are relatively many projects involved,such as close sticking to the bottom,adding layers to the upper cover and so on.Among them,the open-cut method can be used to increase the floor of the upper cover,which can effectively improve the convenience of construction.Taking the structural construction of a subway station as an example,this paper analyzes the key construction technology of the open-cut construction method in the superstructure of the subway station,in order to provide reference for the construction of similar projects.关键词
