Based on GIS, spatio-temporal analysis in quantitative research, has formed a set of analysis methods and the technical process, in view of the leakage defects mechanism research, first analyzes the regional hydrogeological conditions and uplift area distribution and the change of time and space, and then analyzes the groundwater distribution and vertical time-space distribution of underground projects, groundwater is analyzed again and the spatial and temporal distribution and leakage of underground engineering diseases, Finally, the influence degree and correlation between groundwater and underground engineering diseases in this area are obtained.
