• Adjacent structures
• Engineering tests
• Foundation settlement
• Seismic image
• Soil layer
• Surrounding buildings
• Underground cavities

In the water accident of an underground project, the foundation settlement and the cracks of adjacent structures are caused. Safety of surrounding buildings is threatened because of unknown subsidence. The technology of seismic image is applied to tracing test of underground soil in hidden trouble area. The results show that, underground soil layers are affected by water accident, by which multi-point abnormal subsidence and underground cavities are caused. This conclusion is valuable in post repairing and strengthening in hidden trouble area.
