            【Engineering geology】Detection of urban shallow underground abnormal body

            Time:2019-3-8

            Location: Susong Road subway line in Hefei city

            Task: Geological line micro exploration of the base layer of the road

            Operation time: March 8, 2019

            Weather condition: fine

            Operating equipment: GN201E

            Operation parameters: triple circular array observation system, array radius of 1 m-2 M-4 m, 2 Hz broadband geophone, sampling rate of 250 Hz, gain of 0 dB.

            Operation results: the micro motion results accurately detected the location of the underground channel, which corresponded to the drilling results very well.

            Operation site: strong earthquake interference source does not affect the quality of micro motion data acquisition.
