Urban subway tunnel engineering in reducing travel inconvenience and effective utilization of urban underground space has played an important role. Due to the complexity and diversity of metro tunnel construction, the construction safety accidents occur frequently, so the choice of the reasonable construction method to improve its security and the economy is particularly important. In this paper, the construction steps, construction characteristics and applicable conditions of the common subway tunnel construction methods such as open excavation method, cover excavation method and underground excavation method are analyzed and introduced in detail, which has reference significance for the selection of construction methods in the subway tunnel project in the future.
