摘要：
In view of the mechanic characteristics of tunnel-type anchorage (TTA), the research results on the clamping effect, the failure mechanism and stability, the bearing capacity and the dynamic response under seismic action are summarized. TTA can resist the huge pulling force from the main cable under the clamping effect. Based on the clamping effect, the formula of its bearing capacity can be deduced, and the mechanical parameters of surrounding rock, the wedge angle and buried depth of the plug body and other factors will have different degrees of influence on its bearing capacity. The failure of TTA starts from the cementation surface between the bottom of the plug body and surrounding rock, and develops upward in horn shape. Under earthquake, the deformation of the front anchor surface is larger than that of the rear anchor surface. Combined with the existing research contents, the future research directions of TTA mechanical properties are prospected. © 2022, Jilin University Press. All right reserved.
