River storehouse bank slope protection technology, although meeting the requirement of protection, it is considered as " ecological vestige ".But actually their ecology
Effect is poor.From the ecological of material, the artificial material such as concrete, earth working material in use there may be
Some have the material of pollution to water quality of river, and material is not ecological enough in itself；From price and security, these materials
The general higher, intensity of price easily decays with the time, the reasons such as aging and corrosion occurs, these technologies also exist construction costs compared with
High, the shortcomings that long-term safety performance is poor；From using energy source, produce these artificial materials and usually require to consume more energy
Source, or even more serious ground contamination environment, the theory of sustainable development is not met.
With the enhancing of Public environmental attitude, river is improved, the ecological of bank slopes maintenance technology is increasingly becoming main flow.How
The natural materials such as plant, natural block stone are applied in actual river, bank slopes maintenance engineering to be increasingly becoming and are engaged in shore protection neck
Scholar the problem of extremely paying close attention to of domain research, because these natural materials are inherently ecological first, the compatibility with environment
It is good, produce good ecological effect for slope protection works and establish important basis；Secondly, have material source extensively, engineering makes
The advantages that valency is low, construction technology is simple；Furthermore the good endurance of slope protection works.Because the natural block stone selected all is hard
Firmly, the strong rock of weatherability, the factor of building stones strength retrogression can not be considered in the engineering services time limit, moreover,
Plant haulm growth is thicker and plant division effect will make plant to further enhance the restriction effect of block stone displacement, causes domatic anti-
The general safety stability increase of watch box system.
Optimal protection effect can be played for how the materials such as the natural block stone of research, plant combine, generally use
It is field test method, field test typically has the shortcomings that the test period is long, experiment input is high, and in by natural environment
The influence of the external force such as wind load, freeze thawing is big, it is difficult to obtains live data.In order to overcome the shortcomings of field test method, the present invention carries
Go out the indoor simulation device and test method in a kind of river, storehouse bank ecological safeguard structure stabilization and working property.

Embodiment 3：
The present embodiment discloses a kind of experimental method based on the described device of embodiment 1, it is characterised in that including following step
Suddenly：
1) assembled device, the plant stake physical model for needing quantity is plugged in plant stake physical model fixing pipe, planted
The selection of thing stake physical model need to have certain rigidity, can bear the sliding force of bulk solid physical model, and not deform, such as
From galvanized wire.Moving trolley is driven by adjusting screw so that shot block stone physical model installing system is horizontal.By shot
The uniform spreading of block stone physical model is into the rectangle frame of shot block stone physical model installing system.What deserves to be explained is it can not touch
Curved plant stake physical model, if plant stake physical model touched it is curved, can be before shot block stone physical model be leveled by plant stake
Physical model straightening.The spreading upper surface of shot block stone physical model need basic horizontal and with limiting plate along concordant.Work as plant
, can multiple spreading, and it is flat to coordinate geotechnological knife to apply shot block stone physical model upper surface on a small quantity when stake physical model is overstocked.
2) functional reliability for sliding unstability analyzer is examined：It is reliable to its after the power on for sliding unstability analyzer
Property test, make manually conductive contact contact after, if indicator lamp lights, slide unstability analyzer it is effective, can be connect
The experiment got off.If it is indicated that lamp is reactionless, then whether need has electricity, wire whether to connect complete and conductive contact to power supply is
It is no to be checked with beam conduction.In addition, also need to check the rotation on slip unstability analyzer, slide unit, really
Protecting it can be with normal work, coating lubricating oil if necessary.
Slide the installation of unstability analyzer：After the completion of shot block stone physical model arrangement, unstability will be slided using fixed mount
Analyzer is fixed on shot block stone physical model installing structure, after switching on power, will slide unstability gauge head insertion bulk solid thing
Manage in model, and keep the lower edge for sliding lower edge and the bulk solid physical model of unstability gauge head to have to ensure to slide unstability gauge head
The distance normally swung.The center line that unstability gauge head need to be aligned between two avenue system thing stake physical models is slided, not may occur in which deflection.
3) screw mandrel driving moving trolley 142 moves so that shot block stone physical model installing system tilts.In embodiment, need
Will slowly, at the uniform velocity, be rotated intermittently screw mandrel, the change of immediate observation protection body physical model and indicator lamp while rotary screw
Whether light.For guarantee test precision, screw mandrel often rotates a circle, intermittently once, time 30s or so, such as bank slope protection body thing
Changing does not occur in reason model, and continues rotary screw, until bank slope protection body physical model changes.
When shot block stone physical model installing system tilts to certain angle, bulk solid physical model occur it is overall or
