Testing device and testing method suitable for creep property of anchor cable anchoring segment
The invention discloses a testing device and a testing method suitable for a creep property of an anchor cable anchoring segment. In order to fill up the blank of creep property research of the pre-stressed anchor cable anchoring segment and disclose the deformation time effect between an anchor cable and a section of a grouting body, the testing device and the testing method suitable for the creep property of the anchor cable anchoring segment are provided. On the basis of a space axial symmetric equilibrium differential equation, a physical equation and a geometric equation, similar relations of all parameters are provided, and a similitude ratio of a model test is formulated. The testing device is composed of pre-stressed anchor cables (bars), a loaded jack, an anchoring device, anchoring meters, a counter-force frame, the grouting body, a modal groove and anchoring bolts from top to bottom. A monitoring device is composed of a micrometer gauge and a strain gage. According to the testing device, the creep test of the anchoring segment can be stimulated, and the pull-out test of the anchor cables (rods) can be conducted.
