Test device for simulating stratum deformation caused by subway shield tunnel construction

Abstract

The invention relates to the technical field of underground engineering experiment, in particular to a test device for simulating stratum deformation caused by subway shield tunnel construction, comprising a base plate, a test box fixedly connected to one side of the top surface of the base plate, a test stratum laid inside the test box, a tunneling assembly arranged on one side of the test box for performing shield construction on the stratum, a sliding groove opened inside the base plate, an adjusting assembly arranged inside the sliding groove for controlling the movement of the tunneling assembly, a monitoring assembly arranged inside the stratum, and the monitoring assembly electrically connected to a data collector through a cable. The invention lays the test stratum inside the test box, then uses the tunneling assembly simulating shield construction to perform shield construction on the stratum, and then collects the deformation data of the stratum during shield construction through the monitoring assembly, which can effectively simulate the stratum deformation during subway shield tunnel construction; and through the data collected by the data collector, it can explore and solve the impact of shield tunnel construction on the stratum.
