Abstract��
Based on the design practice of subway engineering, this paper summarizes the design schemes for
shield arrival shaft combined with the mined station. Through a comprehensive consideration of factors such as shield hoisting, air duct construction, running tunnel construction, station construction, air duct layout, etc., this paper analyzes the advantages and disadvantages of various schemes and their adaptabilities. Additionally, a scheme is recommended for hoisting a shield out of a shaft by making use of the mined underground shaft, air duct and air shaft considering that it is not possible to set up a separate shaft around a mined station. Through design calculation,the design technology for a large shaft is summarized. The results show that traffic condition, construction period and station form are the main influencing factors for setting a shield arrval shaft, and it is feasible to construct a shield arrival shaft in combination with a station air duct.
