to be processed was 304 stainless steel, which has good processing performance and high toughness, and is widely used. Experimental studies were performed using three-level three-factor orthogonal......
is an underground two-story station with a main length of 180 m and was constructed via island-type excavation. The maximum excavation dimensions of the station tunnel are 22.16 m wide and 19.21 m high... and -7.335 MPa, respectively). Each tunnel is subjected to high compressive stress at the inverted arch, and because of the triangular layout of the tunnel, the arch waist of the running tunnels......
