Abstract

The Suzhou Metro Line 11 is a planned urban rail transit line in Suzhou City. The efficient and safe construction of Line 11 will effectively alleviate the traffic pressure in the urban area, provide convenient and efficient public transportation options, improve traffic congestion, and enhance the convenience and efficiency of citizens’ travel. Based on the geological survey, considering the engineering geological and hydrogeological conditions of the tunnel section between Lianhu Park and Zuchongzhi Road stations on Suzhou Metro Line 11, combined with the experience of similar projects, the construction method of shield tunneling with earth pressure balance technique was determined for the tunnel section. To ensure safe and efficient construction, attention points during shield tunneling construction were also addressed. Based on the cross-sectional diagram of the shield tunnel structure, a calculation model for the segment of the shield tunnel was proposed, determining the reinforcement, reinforcement area, and reinforcement ratio for segments at different burial depths. During the specific construction process, a construction monitoring plan was established for different areas within the major impact zone, minor impact zone, and potential impact zone. Shield tunneling construction in urban environments requires meticulous monitoring to ensure construction quality, mitigate risks to the surrounding environment, and safeguard public safety. Therefore, construction monitoring data points were accordingly arranged. This paper presents an analysis of shield tunneling construction for Suzhou Metro Line 11, focusing on the geological conditions, construction methodologies, and monitoring strategies employed. Through comprehensive monitoring and analysis, the study aims to understand the dynamic changes in soil and water pressure during tunnel excavation, assess the impact of construction on surrounding structures, and optimize construction techniques and parameters. The findings provide valuable insights for future urban tunneling projects, highlighting the importance of proactive monitoring and adaptive construction strategies.
