Abstract
As the urban populations grow, the number and size of subway construction projects are increasing while also meeting higher construction standards. So, subway construction projects must have a better understanding of construction technology. This article focuses on the construction technology of the subway tunnel expansion under the bridge foundation. By analyzing the engineering characteristics of the bridge foundation and using a project as an example, this article provides a detailed discussion of the construction process of tunnel expansion under a bridge foundation. This article aims to serve as a reference for subway tunnel construction in China to ensure the key points of construction technology are understood, thus improving construction quality and laying a solid technical foundation for the sustainable development of urban rail engineering.
