摘　　要：城市轨道交通线网密度不断加大,地下空间综合修建技术得到发展,各类交叉重叠的建设工程问题越来越多,综合管廊、地铁工程同为线性工程,多为盾构施工,盾构掘进施工过程中对周边建(构)筑物产生影响,岩溶区等不良地质尤为突出。文章针对此类问题结合项目具体地质情况研究盾构近接下穿地铁区间隧道相关施工技术,采取合理化措施,为后续工程提供技术管理经验。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.
