Study on the Settlement Ratio of Different Subsections for the Shallow Mining Metro Station with Large-Span

Collapsing accidents have occurred at large metro stations due to the insufficient understanding of geological conditions, construction methods, and the interactions between them. Field monitoring, numerical simulations and comparative analyses have been used to study and predict the settlement ratio of different subsections. The results show that the deformation of the surrounding rock is influenced more by the construction of the first pilot for the upper step than the other pilot; the maximum surface settlement ratio due to the first pilot is about 45%, and 41% for the other side. The effect of the middle pilot is even more with a ratio of 51%, while the combined effect for excavating the middle and lower steps is relatively less with a ratio of 10%. The ground settlement curve resembles declining steps with a final stable value. In the end, the validity and feasibility of this method have been proven by comparing the results with the monitoring data. The design, construction and monitoring of the metro station can be guided by this method in the future, and the structural stability and the safety of the surrounding environment can be guaranteed for large-span shallow mining tunnels.
