摘　　要：在城市地下空间开发中盾构施工工法被越来越广泛地应用,结合市体育馆站—西安路站及西安路站—省博物馆站两个隧道区间,介绍了盾构穿越过程中所面临的问题、影响盾构机选型的不利因素及选型原则。根据两区间洞身地质条件、经济性、适用性、地下水渗透情况及土压盾构和泥水盾构各自的特点等综合因素考虑,最终确定本工程采用土压平衡盾构。The shield construction technique in the urban underground space development is more and more widely used.Combining two interval tunnels of City Stadium Station to Xi'an Road Station,and Xi'an Road Station to Provincial Museum Station,this paper introduces the problems faced in the shield crossing,the adverse factors affected shield selection,and the selection principle.According the comprehensive factors among two interval tunnels such as geological conditions,economical aspect,application ability,groundwater seepage,earth pressure of shield,and the characteristics of slurry shield,it finally identifies that this project by adopting earth pressure balance shield.
