Description
Technical field
The present invention relates to a kind of roadbed side slope supporting construction large-scale model plate test loading system.
Background technology
Retaining structure is to guarantee highway, the effective measure that Railway Bed Slope is stable, to deformation failure pattern, structure and the ground interaction mechanism of the various slope supporting ruggedized constructions such as antislide pile, retaining wall, anchor cable framework, injecting grout through steel perforated pipe, the actual functional performance research of different reinforcing modes has important engineering significance.But due to Rock And Soil and the interactional complexity of works, it is subject to force mode, failure mechanism etc. to be often difficult to obtain breakthrough by theoretical research, employing model testing can be comparatively effective.
At present, in the large-scale model test of retaining structure, be all using vertical load as load mode, by the structural plane of artificial setting, transfer the load to works.But by vertical loading, the size and the distribution form that are delivered to the power on works are all indefinite, to measure and be also difficult to reaction reality by earth pressure gauge, stress strain guage, this causes huge difficulty to large-scale model experimental study of retaining structure.
Summary of the invention
The object of this invention is to provide a kind of horizontal loading system for the test of roadbed side slope supporting construction large-scale model, loading system can be simulated suffered Thrust of Landslide or the soil pressure of retaining structure in actual roadbed side slope.
First the present invention sets up model to the prototype side slope of intending simulating and carries out numerical simulation, obtain the Thrust of Landslide of side slope or the size of soil pressure and the regularity of distribution, will its suitably simplify after as the level input load of model testing, with to roadbed slope supporting structure work shape, deformation mechanism and the supporting effect etc. under active force effect study.
Technical scheme of the present invention is: described horizontal loading system is made up of counter force wall, servo loading cylinder, load plate, guide peg, anchor cable, counter force wall embeds ground, counter force wall top arranges 2 road anchor cables and reinforces, the ground part of counter force wall is provided with multiple servo loading cylinders, one end of servo loading cylinder connects load plate, between counter force wall and load plate, has guide peg.
Servo loading cylinder external part is connected with load plate by ball pivot, and described servo loading cylinder is fixing by the supporting of servo loading cylinder.
Horizontal loading system of the present invention compared with the prior art tool has the following advantages:
1) employing level loads, and can make size and the distribution form of the power on works that is delivered to clearer and more definite;
2) adopt servo loading system hierarchical loading, can reproduce more accurately soil body real bearing state, be conducive to obtain more real experimental data.
3) counter force wall embeds the soil body and reinforces with anchor cable, and displacement is controlled well, little to ambient influnence, and cost is lower.
