rock mass and frame beam with pre-stressed anchor cable. Furthermore, the conception of the best anchorage-angle in pre-stressed anchor cable was proposed. At last, the parameters of the interaction between transverse isotropy rock mass and frame beam with pre-stressed anchor cable were investigated by finite element method, and the best anchorage-angle in pre-stressed anchor cable was obtained......
