The density of urban rail transit line network is continuously increasing,the comprehensive construction technology of underground space is developing,and various cross-overlapping construction project problems are increasing.Both comprehensive utility tunnel and subway project are linear projects,and mostly adopt shield construction.Shield tunneling construction process may affect the surrounding buildings(constructions),and the unfavorable geology such as karst areas is particularly prominent.To address such problems,combined with the specific geological conditions of the project,this paper studies the construction technology related to the shield approaching undercrossing subway section tunnel,and takes reasonable measures to provide technical management experience for subsequent project.
