Investigation on the interaction mechanism and failure behavior between bolt and rock-like mass
Tunnelling and Underground Space Technology（2019）
摘要
•The failure modes of anchorage body under different diameter matching were studied.•Both equations of tensile force and interfacial shear stress were derived.•The distribution of interfacial shear stress and axial stress was analyzed.•The optimal diameter matching difference was obtained.
