Abstract

See full text

The application provides a method for evaluating stability of a tunnel surrounding rock considering creep characteristics of a structural plane, which includes the following steps: S1, discretizing a tunnel surrounding rock region, and constructing a numerical model of a tunnel-surrounding rock structure; S2, initializing the numerical model; S3, presetting a creep time, and obtaining a normal force of a structural plane node based on an initialized numerical model; S4, based on the normal force, obtaining an unbalanced force of a rock mass region element; and S5, judging the unbalanced force of the rock mass region element, and completing a stability evaluation of the tunnel surrounding rock.
