Research On Laboratory Shear Rheological Tests Of Anchorage Interface

Anchorage technology for rock and soil reinforcement technology, has been widelyapplied in engineering construction, especially in the roadway support reinforcement of thecoal mine, shoring of the deep pit slope, dangerous rock, landslide reinforcement, largevolume of dam body and the stability of rock and soil slope. The reinforcement effect isobvious and has obvious economic benefits. Already have a lot of scholars for anchoring themechanical properties of interface to do the relevant research, obtained by theory and test theanchoring interface shear stress distribution, but rarely consider the rheology of anchorageinterface of anchorage system is a balanced stress influence. Therefore research on anchorageinterface rheological test, the rheological characteristics and long-term strength of theanchorage system, to add anchor rock mass stability control is of great realistic significance.Through the device and the system design and modification, interface rheology for anchoranchoring system of drawing test.Main job:In its own RYL-600microcomputer control, on the basis of triaxial creep testingmachine, using the original hardware equipment, microcomputer control system, increase thefamilies moving7016strain acquisition instrument as acquisition system, designed a set ofsuitable for bolt drawing test apparatus. Rebar, mortar, concrete produced six full-lengthbonding type small anchorage system test. USES hierarchical continuous loading of theanchorage system of drawing test. Combined with the experimental results summarized fourtypes of anchorage system. Based on the load transfer method, load transfer of anchorageinterface mechanics model is established, combined with the experiment the interface strainwith the anchor length, load size and the change rules of time, discussed the interface stressincreases with the increasing length direction of the distribution and the change law of time.This paper discusses the rheological effects on interfacial stress transfer mechanism.Respectively from the perspective of the empirical equation and model theory, interface strainconstitutive model is established. With the test result is better fitting effect.And correspondingmodel parameters were discrimination...
