Abstract:
A method for deformation control of large-span tunnel in chlorite schist stratum. The method divides the large deformation of large-span tunnel in chlorite schist stratum into five deformation grades according to the surrounding rock conditions of the tunnel. In response to each deformation grade, the deformation control of large-span tunnel is determined so as to ensure the safety and stability of the tunnel support structure and to avoid the clearance intrusion caused by tunnel deformation.

Claim (Index 5):
The method for deformation control of large-span tunnel in chlorite schist stratum according to  claim 4 , wherein controlling deformation of large-span tunnel with different deformation grades is realized by controlling a row number of advance grouting pipes, a value of reserved deformation, a distance from a bottom of the tunnel invert to a top surface of invert backfill during the excavation process, a model of and the space between the steel frames, a value of reserved deformation, a diameter and quantity of feet-lock pipes, and a thickness of shotcrete and secondary lining concrete of each layer of steel frames.
