Mechanical properties and progressive failure characteristics of sandstone containing elliptical and square openings subjected to biaxial stress
Two kinds of common tunnel shapes, i.e. elliptical opening and square opening were selected for biaxial compression tests, and the influences of two kinds of opening shapes on the mechanical properties, failure characteristics and failure modes of sandstone were compared and analyzed. The complex va...
