| Zusammenfassung: | The invention discloses a shield stratum disturbance detection method which comprises the following steps: before shield construction, performing first micro-motion detection on a shield target section to obtain first wave velocity data of each stratum of the shield target section; after shield construction, performing second micro-motion detection on the shield target section to obtain second wave velocity data of each stratum of the shield target section; according to the first wave velocity data and the second wave velocity data, obtaining the wave velocity change rate of the shield target section in each stratum before and after the shield; and on the basis of the wave velocity change rate of each stratum of the shield target section before and after the shield, judging the disturbance condition of each stratum of the shield target section. The invention provides the shield stratum disturbance detection method. The technical problem that in the prior art, stratum structures need to be damaged when stratum |
