Abstract

The invention belongs to the field of geotechnical engineering, and in particular relates to a model test device for coupling the anchoring force loss of a prestressed anchor rod (cable) and the time-dependent deformation of a slope. It mainly includes a preparation system and a pressurization system. The preparation system includes a mold bottom plate, a mold long side splicing side plate, a mold movable side plate, a mold short side splicing side plate, anchor rod (anchor cable) holes, two fixed chutes, two Steel hinges, brackets, bolts, screws, plastic solid pipes, fixtures, pressurization system including reaction frame, splicing reaction plate, hydraulic jack, thruster, backing plate. The device can make a similar material slope model capable of measuring the coupling effect of anchor rod (anchor cable) prestress loss and rock mass aging deformation.

Description

technical field [0001] The invention relates to the field of geotechnical engineering, in particular to a model test device for coupling the anchoring force loss of a prestressed bolt and the time-dependent deformation of a slope. Background technique [0002] Anchor is the most basic supporting component in contemporary geotechnical engineering. Through the longitudinal tension of the anchor body, it can improve the shortcoming that the tensile strength of rock and soil is far lower than its compressive strength, and it can effectively reinforce the surrounding rock in the At the same time, the surrounding rock supports itself, which is now widely used in engineering technologies such as slopes, tunnels, and dams, and the appearance of prestressed anchors can provide support resistance in time and strengthen the deformation of strata and structures. Control ability is conducive to the stability of rock mass. [0003] However, studies have found that the anchoring force of ...
