Abstract

A size effect test system for the shear strength of an anchored structural surface, including a frame, a normal loading mechanism, a tangential loading mechanism, a sample transport trolley, a height adjustment mechanism, and a supporting force measuring mechanism. The normal loading mechanism is installed on the upper part of the frame and the test Above the sample, the tangential loading mechanism is installed in the middle of the frame and in the middle of the sample, the height adjustment mechanism is installed at the bottom of the frame, the sample transport trolley is located above the height adjustment mechanism, and the supporting force measuring mechanism is located on the right side of the frame. The invention provides a size effect test system for the shear strength of an anchored structural surface that can effectively satisfy the test of multi-scale samples containing anchor rods under a large-span load and has good reliability.

Description

technical field [0001] The invention relates to an anchoring structure surface shear strength size effect test system. Background technique [0002] The anchoring of rock mass is a technique of burying the anchor rod into the rock mass to make it stable. The rock mass anchor rod can give full play to the energy of the rock mass, call and improve the self-pregence and self-stabilizing ability of the rock mass, and greatly reduce the structural burden. Self-weight, saving engineering materials, ensuring construction safety and engineering stability, with significant economic and social benefits, are widely used in the field of construction involving slopes, foundation pits, tunnels, underground engineering, dams, wharfs, coasts, bridges And suspension construction and other projects. [0003] At present, the researches on the mechanical properties of anchors mainly include R. Yoshinaka and P. Egger. The shear dilatancy effect of the joint surface affects the shear strength of...
