Considering that complex construction environments bring more and more challenges to metro construction, and based on the construction of the large-diameter shield-driven tunnel and enlarged station at the North Dongfeng Bridge - Jingshun Road section of Beijing Metro line 14, this paper discusses the problems encountered in the preliminary planning and design stage, such as a limited selection of alignments, a limited selection of construction methods, and rigorous external environment requirements. In this context, the combined construction method of a large-diameter shield-driven tunnel with an enlarged metro station is presented. Based on design optimization, process control, and a construction cost comparison, this construction method is proved to be technically feasible and cost effective.
