Embodiment approach 1
[0268] Implementation mode 1: Large-scale construction tunnel geological surrounding rock convergence deformation monitoring
[0269] The present invention can use two methods to measure the distance of the feature edge to the monitoring of the convergence deformation of the geological surrounding rock of the large-scale construction tunnel: one is to use the convergence meter steel ruler completely, such as figure 1 shown; the second is to use only a small part of the extensometer steel ruler, and the other parts use fixed-length steel wires and special hooks, such as figure 2 shown. Because the present invention only cares about the difference Δl between the subsequent monitoring of the characteristic edge and the initial value during the monitoring process, it is sufficient to use a small section of extensometer steel ruler in order to obtain accurate observation readings from the extensometer.

Embodiment approach 2
[0378] Implementation Mode 2: Deformation Monitoring of Tunnel Floor Uplift
[0379] AB is a vertical line segment, A is located at the top of the tunnel, and B is located at the bottom of the tunnel. Measure the length S of AB directly with an extensometer AB , and with its initial value Compare the amount of change , then use the present invention to measure the vertical displacement y of point A, then the uplift of the base plate is δ AB -y≥0, if the equal sign is established, no uplift of the bottom plate occurs.
