以明挖地铁车站与风道接口结构设计问题为研究对象，结合相关理论及实际工程设计经验，从结构布置、抗浮等角度展开分析与探讨。在此接口的结构设计中，应加强和优化变形缝的布置及接口处梁柱体系的设计，选择合理的设计参数，确保结构安全可靠；地下水位特别高的车站，应做好接口处主体结构局部抗浮验算，采取合理有效的抗浮措施，确保主体结构抗浮满足要求；同时，对预留接口的相关设计问题也进行了探讨。

The structural design of connection interface between opencut metro station and ventilation duct is discussed and analyzed in terms of structural arrangement and antifloating. The authors recommend that: 1) The arrangement of deformation seams and the design of beamcolumn system at connection interface should be strengthened and optimized and rational parameters should be adopted so as to guarantee the safety of the structure. 2) The antifloating calculation and antifloating measures should be strengthened for main structure at connection interface with high groundwater level. The relevant design of reserved interface are discussed as well.
