Reinforcement and Monitoring Measures for Overlapped Shields Crossing underneath Railway Stations
Publication: ICTE 2019
ABSTRACT
Shield tunneling method is widely used in urban metro construction at present. How to control the disturbance of shield construction on overlying soil and adjacent exist railways is an important issue in the development and utilization process of underground space. Based on the project, Shenzhen Metro Line 7 crossing underneath Shenzhen North Railway Station, this paper puts forward a set of reinforcement measures system for overlapped shield crossing underneath railway station. This paper concludes that full-bin mode tunneling, decreasing slag volume, accelerating the shield tunneling speed, and early synchronous grouting are effective methods for controlling stratum deformation, which are verified by field monitoring. The research conclusion can provide some reference for the similar engineering in the future.
