The results show that the cross-sectional damage and ovalization of tunnel lining mainly distribute around the fault plane, and the tectonic stress plays a crucial role in the tunnel's response to strike-slip faulting. With the increasing...

... cable [2, 3]. For the reinforcement of a rock slope with a structural plane, the unstable rock mass will slide along the structural plane and the rock mass will have a strong transverse effect on the anchor cable. Therefore, the sliding and shear resistance of the anchor cable should be considered when...

... of the uplift deformation of the tunnel bottom structure by adjusting the rise span ratio of the inverted arch. The conclusions are as follows: (1) The "weak plane" in layered rock mass produces anisotropy of deformation. The creep speed of the surrounding rock is fast at the initial stage and then stabilizes...

... Abstract One of the main failure modes of rock slope is the instability of the key block formed by cutting combination of structural planes. In view of the block stability and control problem caused by the combination of structural planes in the high and steep rock slope in Southwest China...

These layered rocks exhibit some preferred orientation of fabric or possess distinct bedding planes, which results in transverse isotropic behavior on the macroscale. Because of the anisotropy of rock structure, the layered rocks show...
