Abstract: It is obtained the strata movement law under shield tunnelling construction engineering through similar material model test to monitor the curves over time that the different strata settlement trough and horizontal displacement at the same time taking the No.202 tender of No.2 line in Dalian city subway project as the studying object. The results show that the vertical displacement change of the monitoring points for the different strata can be fitted negative with exponential function. The ground strata disturbance has been produced because the first constructing tunnel and resulting as the ground softening; and the surface settlement of the two tunnels is obviously superimposed larger settlement. The existed underground structures or pipelines will prone to cracks subjected additional shearing when tunnel excavating, so that must taking effective protective measures.

Key words: similar model test, settlement trough curve, horizontal displacement, vertical displacement, strata movement law
