Research on the response feature of tunnel inflow to precipitation in a karstic area
Introducing time series analyses method, this paper takes Tongluoshan long tunnel, constructed in a karstic area, as an example, quantifying its response characteristics to the precipitation by adopting correlation and spectral analysis. Results of this research indicate that the groundwater system has huge storage capacity in the tunnel region with strong regulation and filtering ability, which results in low correlation found between the tunnel inflow and precipitation but with a lag about 12.62 d, concluding that the connectivity between precipitation and tunnel inflow is very weak. These results can offer scientific basis to the prevention and drainage of tunnel inflow.
