Abstract:With the popularization and construction of subway facilities, a large number of subway superstructure buildings have emerged. However, two parts of design and construction are often not synchronized. During the design and construction of the subway superstructures, the protection of the corresponding subway facilities below should be considered. Taking a subway superstructure building in Zhengzhou as an example, the concepts of the structure selection and construction plan determination are discussed, and the influence of the project on the subway facilities below is analyzed.
