The experimental tests are carried out on the strength and deformation characteristics of four typical rock samples of phyllite taken from the northern tunnels of Longmen Mountains of the Chengdou-Lanzhou Railway. The results show that the deformation of the phyllite is strongly influenced by the loading angles related to the beddings and the mineral components of the rocks as well as the confining pressure in 3-D compression. The uniaxial compressive strength of the phyllite changes with the changing of th...
