  Stability Analysis of Twin tunnels By A New Limit Strain Criterion

  Abstract: The Stability of twin tunnels is carried out using the strength reduction method (SRM) based on an ideal elastic-plastic model. However, yield and failure are difficult to differentiate only by stress values in the ideal elastic-plastic model. To address this problem, this paper presents a new limit strain criterion which means the connectivity of zone gets the limit shear or tensile strain. An...
