摘要
新建隧道近距离下穿既有地铁线路时,采取合适的沉降控制措施尤为重要,文章以济南地铁某新建盾构隧道下穿既有地铁线路工程为背景,通过对施工过程的数值模拟,并结合监测数据和盾构施工参数,探讨新建盾构隧道近距离下穿既有地下线路的施工注意事项,验证隧道沉降控制措施的可行性.
Abstract
It is particularly important to take appropriate settlement control measures when a newly-built tunnel passes underneath the existing subway line at a close distance.Based on the project of a newly-built shield tunnel passing underneath the existing subway line in Jinan Metro,this paper discusses the construction precautions of the newly-built shield tunnel passing underneath the existing subway line at a close distance by numerical simulation of the construction process and combined with monitoring data and shield construction parameters,and verifies the feasibility of tunnel settlement control measures.
