| Abstract: | Convergence confinement principle is a theory and a method to explain the process of dynamic interaction between the surrounding rock and the support in a tunnel. The stability of a tunnel can be judged using the principle according to the displacement data measured during tunnel construction,the key to which lies in the basis for judgment of stability,i.e.,the determination of the limit value of displacement. |
