The PBA method is widely used in Beijing subway, which has the advantages of higher flexibility, wider adaptability, higher security and smaller impact on surrounding environment. However, the construction of subway station is difficult when the engineer was under the conditions of large embedded depth and affected by confined water. The construction technology of Beijing Metro line 6 Dongsi Station was summarized in this paper. Difficulties and points in construction were introduced as well as key technologies, and the construction effect was analyzed.
