Dataset for Surface settlement and face stability analysis in multi-tunnel excavation with spatial configuration effects

This dataset supports the research on the interaction and ground deformation of closely spaced triple-parallel tunnels. It includes field monitoring data from a Guangzhou metro station project, the results of 3D numerical simulations (FLAC3D), and the optimization outputs of the modified Peck formula. The data can be used to validate settlement prediction models based on the modified Peck formula.
