Advances in Constructional Engineering

Shield tunneling beneath existing structures constitutes a common engineering challenge in urban underground transportation systems. Effective settlement control remains crucial for ensuring building safety. This study investigates settlement management techniques during shield tunnel construction, with particular focus on prediction, monitoring, and response strategies. By analyzing the impact of different construction methods on settlement, we propose an integrated strategy combining geological conditions, tunnel design, and construction processes. Through case studies, this paper explores emergency response measures during construction, aiming to provide technical guidance and practical experience for similar projects to ensure structural stability and safety throughout the construction process.
