The utility model relates to an experimental multidirectional hierarchical loading device of anchoring system horizontal rigidity, including fix the support frame and model locator, last vertical guiding mechanism, vertical guiding mechanism and the horizontal guiding mechanism of being provided with of fix the support frame, vertical guiding mechanism installs on fix the support frame, and vertical guiding mechanism installs on vertical guiding mechanism, and horizontal guiding mechanism installs on vertical guiding mechanism, vertical, vertical, horizontal guiding mechanism passes through the slide bar and presses the nested installation of level with slider complex form, the model locator is connected in horizontal guiding mechanism one end to press from both sides tight test model, andcorrespond on the guiding mechanism of all directions and be provided with stop nut, adjust in order to realize the accurate of displacement volume. The utility model discloses ingenious applicationframe hiberarchy realized loading device surging, swaying, hung down and swung three degree of freedom shift control, can guarantee applying the in -process of skew simultaneously, test model only moves alone along the specific horizontal degree of freedom, the motion does not take place for all the other degrees of freedom, experimental precision has been guaranteed to the error of having avoidedthe manual operation to produce, has improved model test's efficiency.
