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 10):
The method for deformation control of large-span tunnel in chlorite schist stratum according to  claim 4 , wherein controlling the zero large-deformation of the large-span tunnel comprises:\n constructing advance support using double-row advance grouting pipe; setting reserved deformation to be 10-20 cm; excavating the tunnel using a method of three steps with reserving core soil; constructing primary support, wherein single-layer primary support is carried out for the arch, side wall and invert of the tunnel, wherein the primary support uses HW175-type steel frame with an interval of 90-100 cm and shotcrete with a thickness of 26-28 cm, and the steel frame is set with a double-layer steel mesh; and the arch foot and the wall foot of the upper, middle and lower steps of the steel frame are set with small-diameter double-row feet-lock pipes with a diameter \u226450 mm, and the installation angle of the feet-lock pipe is 20\u00b0-50\u00b0; and constructing secondary lining using reinforced concrete with a thickness of 60-80 cm at the arch, the side wall and the invert of the tunnel.
