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 1):
A method for deformation control of large-span tunnel in chlorite schist stratum, comprising;\n dividing a deformation of a large-span tunnel in chlorite schist stratum into five deformation grades according to surrounding rock conditions of the tunnel, wherein the five large deformation grades are extremely serious large-deformation, serious large-deformation, medium large-deformation, slight large-deformation, and zero large-deformation; and controlling a deformation of the large-span tunnel corresponding to one of the five deformation grades, wherein the extremely serious large-deformation comprises the tunnel surrounding rock being composed of single chlorite schist, having a saturated uniaxial compressive strength Rc<5 MPa, and being in a powder or granular structure; wherein the serious large-deformation comprises the tunnel surrounding rock being composed of chlorite schist and contains 20% of quartz veins, containing underground water, having a saturated uniaxial compressive strength Rc of rock mass of 5-10 MPa, and having a rock mass integrity coefficient Kv\u22640.15, and being in a cataclastic or granular structure; wherein the medium large-deformation comprises the tunnel surrounding rock being composed of chlorite schist and containing less than 20% quartz veins, having no underground water, having a saturated uniaxial compressive strength Rc of rock mass of 10-20 MPa, having a rock mass integrity coefficient Kv of 0.15-0.35, and being in a thin stratified structure with a layer thickness less than 10 cm or a cataclastic structure; wherein the slight large-deformation comprises the tunnel surrounding rock being composed of chlorite schist and contain-sing large quartz veins with particle size greater than 5 cm, having no underground water, having a saturated uniaxial compressive strength Rc of rock mass of 20-25 MPa, having a rock mass integrity coefficient Kv of 0.35-0.55, and being in a thick stratified structure with a layer thickness greater than 10 cm or a blocky structure; and wherein the zero large-deformation comprises the tunnel surrounding rock being chlorite albite schist or other stratum with chlorite as a main part, having no underground water, having a saturated uniaxial compressive strength Rc of rock mass of equal or greater than 25 MPa, having a rock mass integrity coefficient Kv of 0.55-0.75, and being in a blocky structure.
